One of its main goals is to stu dy the >3σ excess observed at low energy (Eν ~ 200-600 MeV) by the MiniB ooNE experiment\, which was located in the same beam.\n\nTwo independent a nalyses are ongoing in MicroBooNE to study this possible excess. \nOne of them uses Deep Learning Convolutional Neural Network (CNN) tools\, origina lly developed for image analysis\, to reconstruct and identify particle tr acks in the (1-proton\, 1-lepton)CCQE neutrino final state topology.\n\nI will first present the detector and discuss the low energy excess seen by MiniBooNE\, then detail the CNN-based event reconstruction with emphasis o n Neural Network techniques and our benchmarking strategy.\n\nhttps://even ts.icecube.wisc.edu/event/82/contributions/5204/ LOCATION:Orchard View (Discovery Building) URL:https://events.icecube.wisc.edu/event/82/contributions/5204/ END:VEVENT BEGIN:VEVENT SUMMARY:Searches for Dark Matter with the Fermi Large Area Telescope DTSTART:20170509T200600Z DTEND:20170509T202400Z DTSTAMP:20260722T073600Z UID:indico-contribution-5205@events.icecube.wisc.edu DESCRIPTION:Speakers: Regina Caputo (UMD/NASA/GSFC)\n\nThe era of precisio n cosmology has revealed that ~80% of the total amount of matter in the un iverse is dark matter. One promising candidate\, motivated by both particl e physics and astrophysics\, is the Weakly Interacting Massive Particle (W IMP). WIMPs are predicted to couple to the Standard Model via annihilation or decay. The annihilation or decay products of particular interest are n eutrinos and gamma rays\, which are detectable by IceCube and the Fermi La rge Area Telescope (Fermi LAT) respectively. Since they do not carry charg e\, they can be traced back to the original source. Indirect searches such as these complement direct and collider (production) searches and are nec essary to fully investigate the particle nature of dark matter. For nearly nine years\, Fermi LAT has been surveying the sky in the energy range 20 MeV to >300 GeV from low Earth orbit. I present several recent results fro m the Fermi LAT Collaboration for a variety of indirect search targets\, i ncluding the dwarf spheroidal galaxies\, and the Galactic center. To date \, the Fermi LAT Collaboration has not detected a convincing WIMP signal a nd hasreported upper limits\, which for some search targets are now challe nging the standard expectations for WIMP dark matter. I will also discuss the prospects with the Fermi LAT and future gamma-ray telescopes.\n\nhttps ://events.icecube.wisc.edu/event/82/contributions/5205/ LOCATION:Northwoods (Union South) URL:https://events.icecube.wisc.edu/event/82/contributions/5205/ END:VEVENT BEGIN:VEVENT SUMMARY:Solar Neutrinos as a Probe of Dark Matter-Neutrino Interactions DTSTART:20170508T213000Z DTEND:20170508T214800Z DTSTAMP:20260722T073600Z UID:indico-contribution-5206@events.icecube.wisc.edu DESCRIPTION:Speakers: Francesco Capozzi (The Ohio State University)\, Ian Shoemaker (University of South Dakota)\, Luca Vecchi (Università di Padov a)\n\nSterile neutrinos at the eV scale have long been studied in the cont ext of anomalies in short baseline neutrino experiments. Their cosmology c an be made compatible with our understanding of the early Universe provide d the sterile neutrino sector enjoys a nontrivial dynamics with exotic int eractions\, possibly providing a link to the Dark Matter (DM) puzzle. Inte ractions between DM and neutrinos have also been proposed to address the l ong-standing "missing satellites" problem in the field of large scale stru cture formation. Motivated by these considerations\, in this paper we disc uss realistic scenarios with light steriles coupled to DM. We point out th at within this framework active neutrinos acquire an effective coupling to DM that manifests itself as a new matter potential in the propagation wit hin a medium of asymmetric DM. Assuming that at least a small fraction of DM has been captured by the Sun\, we show that a sizable fraction of the p arameter space of these scenarios can be probed by solar neutrino experime nts\, especially in the regime of small couplings and light mediators wher e all other probes become inefficient. In the latter regime these scenario s behave as familiar 3+1 models in all channels except for solar data\, wh ere a Dark MSW effect takes place. Solar Dark MSW is characterized by siza ble modifications of the most energetic 8B and CNO neutrinos\, whereas the other fluxes remain largely unaffected.\n\nhttps://events.icecube.wisc.ed u/event/82/contributions/5206/ LOCATION:Orchard View (Discovery Bldg) URL:https://events.icecube.wisc.edu/event/82/contributions/5206/ END:VEVENT BEGIN:VEVENT SUMMARY:Status of Global Fits to Sterile Neutrinos DTSTART:20170508T204500Z DTEND:20170508T210000Z DTSTAMP:20260722T073600Z UID:indico-contribution-5207@events.icecube.wisc.edu DESCRIPTION:Speakers: Janet Conrad (MIT)\n\nRecent short baseline results have indicated anomalies consistent with ~1 eV2 sterile neutrinos.

The LAT's wide field of view and full-sky cov erage make it an excellent instrument for studying anisotropies in the arr ival directions of protons at all angular scales. These capabilities enabl e the LAT to make a full-sky 2D measurement of cosmic-ray proton anisotrop y complementary to many recent TeV measurements\, which are performed by p rojecting onto right ascension.

Consequently\, one reason for deviations\, breaks or\nexcesses in the expected astrophysical power-law neutrino spectrum could be the\nfl ux of such a particle. Motivated by features in the recent 1347-day IceCub e\nhigh energy starting event (HESE) data\, we focus on particular boosted dark\nmatter ($\\chi$) related realizations of this premise\, where $\\ch i$ is assumed\nto be much lighter than\, and the result of\, the slow deca y of a massive\nscalar ($\\phi$) which constitutes a major fraction of the Universe's dark matter\n(DM). We show that this hypothesis\, coupled with a standard power-law\nastrophysical neutrino flux is capable of providing very good fits to the present data\, along\nwith a possible explanation o f other features in the HESE sample: i.e.\, a) the\npaucity of events beyo nd $\\sim 2$ PeV b) a spectral feature resembling\na dip in the 400 TeV--1 PeV region and c) an excess in the $50-100$ TeV region.\n\n(based on 1612 .02834\, "Boosted Dark Matter and its implications for the features in Ice Cube HESE data")\n\nhttps://events.icecube.wisc.edu/event/82/contributions /5210/ LOCATION:Orchard View (Discovery Bldg) URL:https://events.icecube.wisc.edu/event/82/contributions/5210/ END:VEVENT BEGIN:VEVENT SUMMARY:Search for point-like sources in the astrophysical muon neutrino f lux with IceCube DTSTART:20170508T223000Z DTEND:20170508T224500Z DTSTAMP:20260722T073600Z UID:indico-contribution-5211@events.icecube.wisc.edu DESCRIPTION:Speakers: René Reimann (RWTH Aachen)\n\nUsing a sample of neu trino-induced muon track events\, IceCube has confirmed the high-energy di ffuse astrophysical neutrinos flux\, first found in a sample of high energ y starting events. In order to identify the sources of this diffuse flux\, these muon-neutrino events are ideal because of their excellent angular r esolution. Here we present a search for point-like neutrino sources based on the same sample that was used to measure the diffuse high-energy astrop hysical muon-neutrino flux with a livetime of seven years. This high purit y sample is restricted to the Northern hemisphere and consists of ~425000 events with a median angular resolution of ~1° at 1 TeV that decreases to ~0.3° at 1 PeV. In this analysis an unbinned likelihood maximization is used that is optimized for point-like neutrino emission with the same char acteristics as the diffuse muon neutrino flux. The sensitivity improves fo r sources with an $E^{-2}$ spectrum by 30% compared to previous analysis a nd is at a level of $E^2\\partial \\phi/\\partial E = 3\\cdot 10^{-13}\\\, \\mathrm{TeV} \\\, \\mathrm{cm}^{-2} \\\, \\mathrm{s}^{-1}$ .

At the first stage of its evolution\, the fireball contains gluons a s well as $u$ and $d$ quarks. The very high baryochemical potential inhibi ts gluons from fragmenting into $u \\bar u$ and $d \\bar d$\, and so they fragment predominantly into $s \\bar s$ pairs. The hadronization which fol lows this leads to the strong suppression of pions and hence photons\, but allows heavy hadrons to be emitted carrying away strangeness. In this man ner\, the extreme imbalance of hadron-to-photon content provides a way to enhance the muon component of the air shower. I'll also discuss theoretica l systematics from hadronic interaction models used to describe the cascad es of secondary particles produced in the fireball explosion.

Regardless of the production mechanism at the source\, an appreciable amount of tau neutrino s is expected via mixing over astronomical distances. Identification of ta u neutrinos is essential for the precise measurement of the astrophysical neutrino flavor content\, which in turn helps test neutrino oscillation pa radigms over extremely long baselines and possibly shed light on new physi cs beyond the Standard Model. A tau neutrino undergoing charged current in teraction in IceCube will produce two subsequent energy losses: one from t he neutrino-hadron interaction\, and the other from the decay of the secon dary tau lepton. Such double depositions of energy can appear as a causall y connected "double bang" topology for high neutrino energies (>PeV) or as double pulses in the waveforms of photon sensors at lower neutrino energi es (>100 TeV). I will present a recent search for astrophysical tau neutri nos creating double pulses using three years of IceCube data\, and overvie w the ongoing effort to improve the double pulse waveform identification t echniques for future analyses.\n\nhttps://events.icecube.wisc.edu/event/82 /contributions/5217/ LOCATION:Orchard View (Discovery Building) URL:https://events.icecube.wisc.edu/event/82/contributions/5217/ END:VEVENT BEGIN:VEVENT SUMMARY:Telescope Array Experiment DTSTART:20170509T222400Z DTEND:20170509T224200Z DTSTAMP:20260722T073600Z UID:indico-contribution-5218@events.icecube.wisc.edu DESCRIPTION:Speakers: Dmitri Ivanov (University of Utah)\n\nTelescope Arra y (TA) is the largest cosmic ray detector in the Norther hemisphere\, whic h measures primary particles in 4 PeV to 100 EeV range.

To do this\, the analyses use the outer regions of the d etector to identify and reject penetrating muon tracks produced by cosmic ray interactions with the atmosphere. In doing so they can remove atmosphe ric neutrinos and muons. By using the outer regions of the detector to vet o\, the analyses reduce the fiducial volume to the inner part of the detec tor. Here we will discuss a method that is optimized for finding muon neut rinos with a contained vertex and outgoing track. This selection utilizes the high quality directional information of muons to veto incoming events on a case by case basis. Once a trajectory and starting vertex have been d etermined\, the likelihood for not seeing a hit on digital optical modules (DOMs) passed by the trajectory before the starting vertex can be calcula ted based on the observed hits. This opens most of the instrumented volume up for neutrino detection. The results of this technique will provide ide ntifiable astrophysical neutrinos above 10 TeV originating from the southe rn sky. This region is interesting for galactic sources and currently has the weakest sensitivity to neutrino point sources. Expectations from an in itial data sample and simulation assuming potential diffuse and galactic f luxes will be shown. In addition to aiding in the understanding interestin g southern sky sources\, these new events can also assist in providing ins ight to astrophysical neutrino flavor ratios and the diffuse astrophysical flux.\n\nhttps://events.icecube.wisc.edu/event/82/contributions/5225/ LOCATION:Orchard View (Discovery Building) URL:https://events.icecube.wisc.edu/event/82/contributions/5225/ END:VEVENT BEGIN:VEVENT SUMMARY:Results from Fermi DTSTART:20170508T143000Z DTEND:20170508T150000Z DTSTAMP:20260722T073600Z UID:indico-contribution-5226@events.icecube.wisc.edu DESCRIPTION:Speakers: Marco Ajello (Clemson University)\n\na\n\nhttps://ev ents.icecube.wisc.edu/event/82/contributions/5226/ LOCATION:Forum (Discovery Building) URL:https://events.icecube.wisc.edu/event/82/contributions/5226/ END:VEVENT BEGIN:VEVENT SUMMARY:Multi-PeV Signals from a New Astrophysical Neutrino Flux Beyond th e Glashow Resonance DTSTART:20170508T213000Z DTEND:20170508T214500Z DTSTAMP:20260722T073600Z UID:indico-contribution-5227@events.icecube.wisc.edu DESCRIPTION:Speakers: Ranjan Laha (KIPAC\, Stanford University and SLAC Na tional Accelerator Laboratory\, USA)\n\nThe IceCube neutrino discovery was punctuated by three showers with $E_\\nu$ ~ 1-2 PeV. Interest is intense in possible fluxes at higher energies\, though a marked lack of $E_\\nu$ ~ 6 PeV Glashow resonance events implies a spectrum that is soft and/or cut off below ~few PeV. However\, IceCube recently reported a through-going tr ack event depositing 2.6 $\\pm$ 0.3 PeV. A muon depositing so much energy can imply $E_{\\nu_\\mu} \\gtrsim$ 10 PeV. We show that extending the soft $E_\\nu^{-2.6}$ spectral fit from TeV-PeV data is unlikely to yield such an event. Alternatively\, a tau can deposit this much energy\, though requ iring $E_{\\nu_\\tau}$ ~10x higher. We find that either scenario hints at a new flux\, with the hierarchy of $\\nu_\\mu$ and $\\nu_\\tau$ energies s uggesting a window into astrophysical neutrinos at $E_\\nu$ ~ 100 PeV if a tau.

Searches for astrophysical neutrino sources have focused on trac k events due to the significantly better angular resolution of track recon structions. To date\, no such sources have been confirmed. In this talk we turn our attention to complementary and statistically-independent sourc e searches using cascade events with deposited energies as small as 1 TeV. Compared to the classic approach using tracks\, the cascade channel offe rs improved sensitivity to sources in the southern sky\, especially if the emission is spatially extended or follows a soft energy spectrum. We wil l show results from a first search using 263 cascades collected from May 2 010 to May 2012\, as well as projected sensitivity estimates for an upcomi ng analysis of six years of data.\n\nhttps://events.icecube.wisc.edu/event /82/contributions/5250/ LOCATION:Forum (Discovery Building) URL:https://events.icecube.wisc.edu/event/82/contributions/5250/ END:VEVENT BEGIN:VEVENT SUMMARY:Radio Phased Arrays for the Detection of High Energy Neutrinos DTSTART:20170509T224500Z DTEND:20170509T230000Z DTSTAMP:20260722T073600Z UID:indico-contribution-5251@events.icecube.wisc.edu DESCRIPTION:Speakers: Eric Oberla (KICP University of Chicago)\, Abigail V ieregg (KICP University of Chicago)\n\nGround-based radio arrays offer a p romising future for the detection of high energy neutrinos\, including the prospect of reducing the energy threshold of the radio detection techniqu e to a level necessary to overlap with the high-energy range probed by Ice Cube ($\\sim$10-100~PeV).

This talk will summarize Daya Bay’s most recent resul t\, which presents observations of correlations between reactor core fuel evolution and changes in the detected reactor antineutrino flux and energy spectrum. Four antineutrino detectors in two experimental halls were used to identify 2.2 million inverse beta decays (IBDs) over 1230 days spannin g multiple fuel cycles for each of Daya Bay’s six 2.9 GW reactor cores. A 10σ variation in IBD yield was found to be energy-dependent\, rejecting the hypothesis of a constant antineutrino energy spectrum at 5.1 standard deviations. While measurements of the energy-dependence of this variation show general agreement with predictions from recent reactor models\, the variation in integrated IBD yield disagrees with recent predictions at 3.1 σ. This discrepancy indicates that an overall deficit in measured flux wi th respect to predictions does not result from equal fractional deficits f rom the primary fission isotopes 235U\, 239Pu\, 238U\, and 241Pu.

CR s with energies between 3 × 1015 and 1018 eV\, which we dub the "shin\," have an unknown origin. It has been proposed that DSA at galactic wind ter mination shocks\, rather than at SNR shocks\, may accelerate CRs to these energies. Our work uses the galactic wind model of Bustard et al. (2016) t o analyze whether galactic wind termination shocks may accelerate CRs to s hin energies within a reasonable acceleration time and whether such CRs ca n subsequently diffuse back to the Galaxy\, where they can interact with d ense ambient material to produce gamma-rays and neutrinos. I will argue fo r acceleration times on the order of 100 million years rather than a few b illion years\, as assumed in some previous works\, and I will outline our analytic formulae\, applicable to any wind model\, for CR acceleration. Ev en with generous assumptions\, we find that very high wind velocities are required to set up the necessary conditions for acceleration beyond 1017 e V. We also estimate the luminosities of CRs accelerated by outflow termina tion shocks\, including estimates for the Milky Way wind.\n\nhttps://event s.icecube.wisc.edu/event/82/contributions/5273/ LOCATION:Forum (Discovery Building) URL:https://events.icecube.wisc.edu/event/82/contributions/5273/ END:VEVENT BEGIN:VEVENT SUMMARY:Applying Non-Poissonian Template Fitting to search for point sourc es in IceCube.
