The instrument consists in 885 photo-multiplier tubes arra nged in a 3d-array of 12 lines and is optimized for up-going neutrino dete ction\, having full coverage of our Galaxy centre. The results include lim its from searches for steady and transient sources of neutrinos as well as from searches for a diffuse neutrino flux and for neutrinos from dark mat ter annihilation in the Sun\, which have been conducted using several year s of data. In addition\, particle physics analysis done in ANTARES will be discussed.\n\nhttps://events.icecube.wisc.edu/event/46/contributions/2916 / URL:https://events.icecube.wisc.edu/event/46/contributions/2916/ END:VEVENT BEGIN:VEVENT SUMMARY:Results from the T2K long baseline neutrino experiment DTSTART:20130513T192500Z DTEND:20130513T195000Z DTSTAMP:20260417T161200Z UID:indico-contribution-2917@events.icecube.wisc.edu DESCRIPTION:Speakers: Casey Bojechko (University of Victoria)\n\nRecent me asurements of a non-zero $\\theta_{13}$ are very exciting\, since the resu lts provide an opportunity to study CP violation with neutrinos. One of t hese results comes from the Tokai-to-Kamioka (T2K) long-baseline neutrino- oscillation experiment. The experiment is designed to search for $\\nu_e$ appearance ($\\theta_{13}$) and to precisely measure $\\nu_{\\mu}$ disap pearance ($\\Delta m^2_{23}$\, $\\theta_{23}$) by sampling an off-axis\, h igh purity\, muon neutrino beam. The neutrinos are detected 295km from p roduction by the Super Kamiokande (SK) detector. A near detector 280m from the production target measures the unoscillated beam to improve the preci sion of the oscillation measurements. In this talk I will present up to da te physics results from T2K\, focusing on the $\\nu_e$ appearance and $\\ nu_{\\mu}$ disappearance measurements.\n\nhttps://events.icecube.wisc.edu/ event/46/contributions/2917/ LOCATION:Landmark - 3rd Level URL:https://events.icecube.wisc.edu/event/46/contributions/2917/ END:VEVENT BEGIN:VEVENT SUMMARY:The XENON100 experiment DTSTART:20130513T221200Z DTEND:20130513T223000Z DTSTAMP:20260417T161200Z UID:indico-contribution-2918@events.icecube.wisc.edu DESCRIPTION:Speakers: Kyungeun Lim (UW-Madison)\n\nXENON100 is a dual-phas e (liquid-gas) time projection chamber (TPC) containing a total of 161 kg of LXe with a 62 kg WIMP target mass\, built with radiopure materials to a chieve an ultra-low electro- magnetic background and operated at the Labor atori Nazionali del Gran Sasso in Italy. 224.6 live days of data acquired during 2011 and 2012 have resulted in the most stringent limits on the spi n-independent elastic WIMP-nucleon cross sections for WIMP masses above 8 GeV/c2.

Paired with KamLAND\, t he experiment can observe over 800 thousand inverse beta-decay events in f ive years and do a decisive test of the current hints for sterile neutrino . Daedalus is a phased program leading to a high-sensitivity search for C P violation. The experiment uses a set of high-intensity 800 MeV cyclotro ns to produce pion DAR neutrino sources at several locations (1.5km\, 8km\ , and 20km) going to a single ultra-large\, underground detector with free protons. The Daedalus experiment will provide a high-statistics antineutr ino data set with no matter effects that can be combined with long-baselin e data sets to provide enhanced sensitivity to CP violation and matter eff ects.\n\nhttps://events.icecube.wisc.edu/event/46/contributions/2922/ LOCATION:Varsity I - 2nd Level URL:https://events.icecube.wisc.edu/event/46/contributions/2922/ END:VEVENT BEGIN:VEVENT SUMMARY:Recent Reactor-Based Measurements of Theta13 DTSTART:20130514T190000Z DTEND:20130514T192000Z DTSTAMP:20260417T161200Z UID:indico-contribution-2923@events.icecube.wisc.edu DESCRIPTION:Speakers: David Webber (University of Wisconsin-Madison)\n\nSe veral recent experiments have measured a significant deficit in electron a ntineutrinos at distances of 1-2 km from nuclear reactors. In the 3-neutr ino framework\, this deficit is attributed to a nonzero mixing angle theta 13. Three ongoing experiments\, Double Chooz\, RENO\, and Daya Bay\, cont inue to improve their experimental precision.

The talk will cover hints for an excess of neutrinos above the atmospheric spectrum seen in recent I ceCube analyses and discuss the observation of two neutrinos at an energy of about 1 PeV\, above the expectation from atmospheric neutrino fluxes. A dedicated all-flavor all-sky search for similar neutrinos at lower energi es\, down to approximately 100 TeV\, will be presented. Using a veto techn ique selecting for starting tracks and cascade-like events\, this analysis is able to suppress the downgoing atmospheric neutrino and muon backgroun d\, making it possible to lower the energy threshold for the southern sky more than an order of magnitude to below 100 TeV. Assuming the two observe d PeV events are from an astrophysical flux\, up to several dozen more eve nts are expected and therefore these observations should help to clarify t he origin of the PeV flux.\n\nhttps://events.icecube.wisc.edu/event/46/con tributions/2924/ LOCATION:Marquee - 2nd Level URL:https://events.icecube.wisc.edu/event/46/contributions/2924/ END:VEVENT BEGIN:VEVENT SUMMARY:Status and Outlook for LBNE DTSTART:20130514T190000Z DTEND:20130514T192500Z DTSTAMP:20260417T161200Z UID:indico-contribution-2925@events.icecube.wisc.edu DESCRIPTION:Speakers: Jon Urheim (Indiana University)\n\nThe LBNE long-bas eline neutrino oscillation experiment has been proposed as a major program in beam neutrino and non-accelerator physics that will explore neutrino f lavor mixing and CP violation\, nucleon decay\, and supernova neutrino bur sts\, with sensitivities beyond those of experiments currently in operatio n or under construction. Characterizing its key features\, LBNE can be de scribed as (1) a very large liquid argon TPC far detector\, sited in (2) a laboratory deep underground in the Homestake Mine\, providing (3) a nearl y optimal baseline for oscillation physics for (4) a new 2.3-MW capable be am line located at Fermilab along with (5) a fully outfitted near detector complex.

Traditional direct detection experiments have thus been designed to search for WIMPs in the mass range of several 10's to 1000's of GeV. Ho wever\, in past years there have been a series of direct detection experim ents reporting excess events over background at the lowest recoil energies . The most recent of these is CDMS II\, which reported 3 candidate Si rec oils over an expected background of ~0.5 events. Taken at face value\, th ese results seem to be hinting at a signal from a WIMP of mass ~10 GeV. At the same time\, other direct detection experiments do not see a signal consistent with these findings. Reconciling these observations has been a high priority in both the experimental and theoretical communities for so me time now. I will review the status of recent searches for light WIMPs . I will also discuss future experimental efforts\, which aim to clarify this confusing yet exciting situation.\n\nhttps://events.icecube.wisc.edu/ event/46/contributions/2926/ LOCATION:The Marquee - Level 2 (Union South) URL:https://events.icecube.wisc.edu/event/46/contributions/2926/ END:VEVENT BEGIN:VEVENT SUMMARY:MiniBooNE: current evidence for neutrino oscillations and a futur e test DTSTART:20130514T210000Z DTEND:20130514T212500Z DTSTAMP:20260417T161200Z UID:indico-contribution-2946@events.icecube.wisc.edu DESCRIPTION:Speakers: Rex Tayloe (Indiana U.)\n\nThe MiniBooNE experiment\ , located at Fermilab on the Booster Neutrino Beamline\, has searched for $\\nu_\\mu \\rightarrow \\nu_e$ and\n$\\overline{\\nu}_\\mu \\rightarrow \ \overline{\\nu}_e$ oscillations in the range $0.1<\\Delta m^2<5.0$~ev$^2$ as indicated by results from the LSND experiment. MiniBooNE has recently c ompleted $\\overline{\\nu}_{\\mu}$ running after collecting $11.3 \\times 10^{20}$ protons-on-target (POT). Combining those results with previously collected $\\nu_\\mu$ data from $6.5 \\times 10^{20}$ POT yields a $3.8\\s igma$ excess over background\, consistent with that expected from the LSND result. A proposed followup experiment\, MiniBooNE+\, will test the osc illation signal hypothesis by searching for final state neutrons.\n\nhttps ://events.icecube.wisc.edu/event/46/contributions/2946/ LOCATION:Varsity I - 2nd Level URL:https://events.icecube.wisc.edu/event/46/contributions/2946/ END:VEVENT BEGIN:VEVENT SUMMARY:Galactic Sources in the Fermi Large Area Telescope DTSTART:20130514T195000Z DTEND:20130514T201500Z DTSTAMP:20260417T161200Z UID:indico-contribution-2927@events.icecube.wisc.edu DESCRIPTION:Speakers: Elizabeth Hays (NASA GSFC)\n\nIn the past four years the Fermi Large Area Telescope (LAT) has detected a variety of Galactic s ources of high energy gamma rays. Many of these source types were establis hed or anticipated as gamma-ray emitters before the launch of Fermi\, such as pulsars and their wind nebulae\, supernova remnants\, and high mass X- ray binaries. In these sources the LAT is revealing spectral details and f or some sources resolving spatial features that clarify the origin of the gamma rays. As the LAT catalog grows\, population studies provide further insight into the mechanisms and conditions giving rise to high energy emis sion. The LAT has also discovered new phenomena\, including several Galact ic novae\, which were not generally expected to emit GeV gamma rays. Both the AGILE observatory and LAT have also observed surprising and extreme va riability in the Crab nebula\, formerly thought to be steady enough for us e in calibrations. I will present the current LAT view of the Galaxy\, foc using in particular on results relevant to studying particle content and a cceleration in these regions.\n\nhttps://events.icecube.wisc.edu/event/46/ contributions/2927/ LOCATION:Northwoods - 2nd Level URL:https://events.icecube.wisc.edu/event/46/contributions/2927/ END:VEVENT BEGIN:VEVENT SUMMARY:Double Beta Decay: A Very Important and Difficult Experiment: Gior gio Gratta\, Stanford University DTSTART:20130513T142000Z DTEND:20130513T144500Z DTSTAMP:20260417T161200Z UID:indico-contribution-2928@events.icecube.wisc.edu DESCRIPTION:https://events.icecube.wisc.edu/event/46/contributions/2928/ LOCATION:The Marquee - Level 2 (Union South) URL:https://events.icecube.wisc.edu/event/46/contributions/2928/ END:VEVENT BEGIN:VEVENT SUMMARY:Neutrino Measurements in the Making DTSTART:20130513T201000Z DTEND:20130513T203000Z DTSTAMP:20260417T161200Z UID:indico-contribution-2929@events.icecube.wisc.edu DESCRIPTION:Speakers: Jenny Thomas (University College of London)\n\nThere are a number of options utilizing the NuMI neutrino beam which are being looked at\, which can provide information on deltaCP and even the mass hie rarchy\, in the next decade.

Unlike a large high powered active device\, i.e.\, an ice-penetrat ing radar\, this instrument is a passive receiver of a naturally occurring signal generated by interactions of deep penetrating cosmic ray neutrinos . It is therefore potentially less massive and requires less power\, maki ng it very attractive for outer planet missions. We discuss the basic conc ept and consider the instrument design requirements from the perspective o f a NASA Outer Planet Orbiter Mission. We show results [1] of simulations\ , compare signal-to-noise estimates\, and examine possible components and configurations for the antenna\, receiver\, and electronics. We note some options that can be used to reduce mass and power. Finally\, we identify i ssues that would need further study to produce a more concrete design. \n[ 1] Miller\, T.\, Schaefer\, R.K.\, and Sequeira\, H.B.\, Icarus\, 220\, 87 7-888\, 2012.\n\nhttps://events.icecube.wisc.edu/event/46/contributions/29 30/ LOCATION:The Marquee - 2nd Level URL:https://events.icecube.wisc.edu/event/46/contributions/2930/ END:VEVENT BEGIN:VEVENT SUMMARY:Latest Results on Searches for Dark Matter from IceCube DTSTART:20130513T193600Z DTEND:20130513T195400Z DTSTAMP:20260417T161200Z UID:indico-contribution-2931@events.icecube.wisc.edu DESCRIPTION:Speakers: Matthias Danninger (Stockholm University)\, Collabor ation The IceCube (IceCube Neutrino Telescope)\n\nThe cubic-kilometer size d IceCube neutrino observatory\, constructed in the glacial ice at the Sou th Pole\, offers new opportunities for neutrino physics with its in-fill a rray "DeepCore".

Such a search can shed light on the Majorana nature of the neutrino (whether the neutrino is its own anti-particle)\, the absolute mass scale of neutrinos \, and beyond standard model processes that violate lepton number conserva tion. The first phase of the experiment\, EXO-200\, uses 200 kg of xenon with 80% enrichment in 136Xe in a single-phase liquid xenon time projectio n chamber (TPC). The double beta decay of xenon is detected in the ultra- low background TPC by collecting both the scintillation light and the ioni zation charge. The detector has been taking low background physics data wi th enriched xenon at the Waste Isolation Pilot Plant (WIPP) in New Mexico since early May 2011. The collaboration has produced two high impact physi cs results\, the first observation of two-neutrino double beta decay of 13 6Xe and a neutrinoless double beta decay search result that places one of the most stringent limits on the effective Majorana neutrino mass.

Nonzero values for theta_13 break a ν_ μ-ν_τ symmetry\, which has qualitative as well as quantitative implicat ions for the time-evolution of neutrino flavors. In particular\, the large -distance flavor evolution matrix\, non-invertible with ν_μ-ν_τ symmet ry\, becomes invertible. This means that measurements of neutrino flavor r atios at Earth can now be inverted to directly reveal the flavor ratios in jected at cosmically distant sources. With the updated values of the three neutrino mixing angles\, we obtain the inverted large-distance evolution matrix and use it to derive several phenomenological relations between the injection flavor ratios and the observable ratios at Earth.

It is being built in the Undergrou nd Laboratory of Canfranc\, in the Spanish Pyrenees and it is going to sta rt commissioning in late 2013- beginning of 2014\, after a successful R&D period developed with prototypes.\nNEXT-100 is an electroluminescent\, asy mmetric TPC which is going to host 100 kg of the Xe-136 isotope at 15 bar of pressure. Its original concept consists of the use of electroluminescen ce as an amplification mean and two separated-function capabilities for en ergy measurement and tracking. On one side\, a sparse array of photomultip liers records both the primary scintillation signal\, which gives the star ting time of the event\, and the total deposited energy\, while\, on the other side\, a dense grid of silicon photomultipliers provides the reconst ruction of the position. Being able of reconstructing the position is doub ly useful: one hand\, it allows the correction of the energy of the event\ , which is distortioned according to the position\, and on the other hand it provides an extra handle for background rejection\, since the topology is different for the signal and the principal backgrounds.\n\nThe two NEXT protoypes currently running have already demonstrated an energy resolutio n that extrapolates to 0.5-0.8% FWHM at the Qbb energy. Also\, a a backgro und count lower than 8 x 10^-4 c/(kg*keV*yr) is estimated for NEXT-100\, a ccording to the tracking capability and the radiopurity measurements of th e materials being used for the NEXT-100 construction.

UHE neutrinos can be detected w ith a variety of techniques. In particular\, neutrinos can interact in the atmosphere (downward-going neutrinos) or in the Earth crust (Earth-skimmi ng neutrinos)\, producing air showers that can be observed with arrays of detectors at the ground. With the Surface Detector Array of the Pierre Aug er Observatory we can detect these types of cascades. The distinguishing s ignature for neutrino events is the presence of very inclined showers prod uced close to the ground (i.e. after having traversed a large amount of at mosphere). In this work we review the procedure and criteria established t o search for UHE neutrinos in the data collected with the ground array of the Pierre Auger Observatory. This includes Earth-skimming as well as down ward-going neutrinos. No neutrino candidates have been found\, which allow s us to place competitive limits to the diffuse flux of UHE neutrinos in t he EeV range and above.\n\nhttps://events.icecube.wisc.edu/event/46/contri butions/2953/ URL:https://events.icecube.wisc.edu/event/46/contributions/2953/ END:VEVENT BEGIN:VEVENT SUMMARY:Recent Results from the Fermilab MIPP Experiment and Future Nitrog en Run DTSTART:20130514T221000Z DTEND:20130514T222500Z DTSTAMP:20260417T161200Z UID:indico-contribution-2964@events.icecube.wisc.edu DESCRIPTION:Speakers: Nickolas Solomey (Wichita State University)\n\nWe wi ll review recent new cross-section measurements from the Fermilab MIPP exp eriment.

Data from cosmic ray observatories are y et inconclusive about their exact location or distribution\, but provide a measure for the average local density of these emitters. Due to the discr eteness of the emitters the flux and nuclear composition is expected to sh ow ensemble fluctuations on top of the statistical variations\, i.e. “co smic variance." This effect is strongest for the most energetic cosmic ray s due to the limited propagation distance in the cosmic radiation backgrou nd and is hence a local phenomenon. For the statistical analysis of cosmic ray emission models it is important to quantify the possible level of thi s variance. In this work we study the sensitivity of the Pierre Auger Obse rvatory and the JEM-EUSO space mission to ensemble fluctuations on the ass umption of uniform distribution of sources\, with local source density $\\ sim 10^{-5}~{\\rm Mpc}^{-3}$. We show that if the Auger experimental perfo rmance is in line with design expectations\, then after 15 years of data c ollection (i.e. by 2020) the experiment will attain sensitivity to observe spectral fluctuations in the cosmic ray energy spectrum at Earth relative to the overall power-law fit if the nearest source(s) are at 3 Mpc. We al so show that with data taken until 2025 the Auger experiment will become s ensitive to ensemble fluctuations if the nearest sources are 10 Mpc away. Finally\, we demonstrate that in only one year of observation JEM-EUSO wil l be able to probe ensemble fluctuations if the nearest sources are at 3 M pc\, and that after 3 years orbiting the Earth this pathfinder mission wil l become sensitive to ensemble fluctuations if the nearest sources are 10 Mpc away. The study of spectral fluctuations from the local source distrib utions are complementary but independent of on-going cosmic ray anisotropy studies.\n\nhttps://events.icecube.wisc.edu/event/46/contributions/2955/ LOCATION:The Marquee - 2nd Level URL:https://events.icecube.wisc.edu/event/46/contributions/2955/ END:VEVENT BEGIN:VEVENT SUMMARY:Towards a Megaton MeV Neutrino Detector DTSTART:20130513T221500Z DTEND:20130513T223000Z DTSTAMP:20260417T161200Z UID:indico-contribution-2957@events.icecube.wisc.edu DESCRIPTION:Speakers: Sebastian Böser (Universität Bonn)\, Marek Kowalsk i (Humboldt University)\, Markus Voge (Bonn University)\, Lukas Schulte (o =bonn\,ou=Institutions\,dc=icecube\,dc=wisc\,dc=edu)\, Nora Linn Strotjoha nn (Universität Bonn)\n\nThe observation of neutrinos from SN1987A has sp awned hundreds of publications\, underlining the importance that SNe and n eutrinos play in cosmology\, astrophysics and particle physics.

Receiver stations locat ed adjacent to the observatory sample the RF environment at 250 Megasample s per second\, and employ smart triggering algorithms to record candidate air shower echoes.

This e lectron-positron wind is also the energy source of the un-pulsed TeV emiss ion in the pulsar wind nebulae (PWN). Therefore\, a tight correlation betw een the pulsed GeV emission and un-pulsed TeV emission might be expected. The work we will present in this talk shows that there is no obvious corr elation between TeV flux of un-pulsed emission and GeV flux of pulsed emi ssion. Instead\, a tight correlation was identified when the GeV flux and TeV flux were normalized by suitable functions of pulse period and spin-do wn luminosity. Interpretation of this normalization is still an open quest ion. In this talk we will present the possible interpretations.\n\nhttps:/ /events.icecube.wisc.edu/event/46/contributions/2992/ LOCATION:Northwoods - 3rd Level URL:https://events.icecube.wisc.edu/event/46/contributions/2992/ END:VEVENT BEGIN:VEVENT SUMMARY:CUORE neutrinoless double beta decay experiment DTSTART:20130513T192000Z DTEND:20130513T194000Z DTSTAMP:20260417T161200Z UID:indico-contribution-2993@events.icecube.wisc.edu DESCRIPTION:Speakers: Yuan Mei (Lawrence Berkeley National Laboratory)\n\n Neutrinoless double beta decay\, a rare nuclear process\, if found\, would confirm the Majorana nature of neutrinos. Successful observation of neut rinoless double beta decay would require a detector with substantial amoun t of candidate isotope\, as well as excellent energy resolution and extrem ely low background. The CUORE (Cryogenic Underground Observatory for Rare Events) experiment aims at addressing all these challenges with low tempe rature bolometers. CUORE is currently being constructed underground at La boratori Nazionali del Gran Sasso (LNGS) in Italy. It packs 988 TeO2 crys tals of 5x5x5 cm3 each\, totaling 741 kg of detection mass\, of which the candidate isotope Te-130 is 204 kg. The whole detector will be cooled dow n to a base temperature of 10 mK and the particle interaction signal will be read out from temperature rise of each crystal due to energy release. The first tower\, CUORE-0\, is currently taking data.\n\nI'll give an intr oduction to the CUORE experiment and update on its current status.\n\nhttp s://events.icecube.wisc.edu/event/46/contributions/2993/ URL:https://events.icecube.wisc.edu/event/46/contributions/2993/ END:VEVENT END:VCALENDAR
