Prof. INA SARCEVIC (University of Arizona)08/05/2017, 14:30Dark Matter - Convenor: Carsten Rott, SKKUThe IceCube detection of High Energy Starting Events (HESE) and the upward muon track events (6 year data) are presently hard to explain with the single power-law astophysical flux for energies above 30TeV. We investigate the possibility that a significant component of the additional neutrino flux originates due to the decay of a very heavy dark matter particle via several possible...Go to contribution page

Prof. Rajesh Gandhi (HRI)08/05/2017, 14:48Dark Matter - Convenor: Carsten Rott, SKKUWe study the implications of the premise that any new, relativistic, highly energetic neutral particle that interacts with quarks and gluons would create cascade-like events in the IceCube (IC) detector which would be observationally indistinguishable from neutral current deep-inelastic (DIS) scattering events due to neutrinos. Consequently, one reason for deviations, breaks or excesses...Go to contribution page

Dr Aaron Vincent (Imperial College London)08/05/2017, 15:06Dark Matter - Convenor: Carsten Rott, SKKUThe origin of the observed extraterrestrial neutrinos is still unknown, and their arrival directions are compatible with an isotropic distribution. This observation, together with dedicated studies of Galactic plane correlations, suggest a predominantly extragalactic origin. Dark matter-neutrino interactions, which have been extensively studied in cosmology, would thus lead to a slight...Go to contribution page

Hrvoje Dujmovic (o=sungkyunkwan,ou=Institutions,dc=icecube,dc=wisc,dc=edu)08/05/2017, 15:24Dark Matter - Convenor: Carsten Rott, SKKUSearch for heavy dark matter decay with IceCube Many heavy (m>100TeV) dark matter models predict the dark matter particle to decay into standard model particles, including neutrinos. These neutrinos would produce a unique signal, both in terms of their energy and angular distributions, in the IceCube detector. This talk describes the search for such a signal using two years of high energy...Go to contribution page

Antonia Hubbard (Northwestern)08/05/2017, 15:42Dark Matter - Convenor: Carsten Rott, SKKUThe Micro-X sounding rocket uses a Transition Edge Sensor (TES) array to make X-ray observations. The improved energy resolution of TESs compared to traditional space-based X-ray detectors brings new precision to both supernova observations and the X-ray search for sterile neutrino dark matter. Current X-ray observations disagree over the potential presence of a 3.5 keV X-ray line consistent...Go to contribution page

Dr Francesco Capozzi (The Ohio State University)08/05/2017, 16:30Dark Matter - Convenor: Carsten Rott, SKKUSterile neutrinos at the eV scale have long been studied in the context of anomalies in short baseline neutrino experiments. Their cosmology can be made compatible with our understanding of the early Universe provided the sterile neutrino sector enjoys a nontrivial dynamics with exotic interactions, possibly providing a link to the Dark Matter (DM) puzzle. Interactions between DM and neutrinos...Go to contribution page

Dr Carlos Arguelles (o=mit,ou=Institutions,dc=icecube,dc=wisc,dc=edu)08/05/2017, 16:48Dark Matter - Convenor: Carsten Rott, SKKUIn this talk I will discuss the production of high-energy neutrinos from interactions of cosmic rays with the solar atmosphere. Production of solar atmospheric neutrinos has been previously considered in the literature both as a potential source of high-energy neutrinos and as an irreducible background for dark matter searches. In our new calculation we estimate the uncertainties that arise...Go to contribution page

Jay Hyun Jo (Yale University)08/05/2017, 17:06Dark Matter - Convenor: Carsten Rott, SKKUDM-Ice is a phased experimental program using low-background NaI(Tl) crystals with the aim to unambiguously test the claim of dark matter detection by the DAMA experiment. DM-Ice17, consisting of 17 kg of NaI(Tl), has been continuously operating at a depth of 2457 m in the South Pole ice since December 2010. COSINE-100 is a joint collaboration between the DM-Ice and KIMS groups to search for...Go to contribution page

TheDarkSide-50 detector is a two-phase argon TPC installed at the center of two nested veto detectors, a 30-tonne liquid scintillator neutron veto and a 1,000-tonne water Cherenkov muon veto. While operating in 2014 with a fill of argon extracted from...Go to contribution page

Prof. Ali Murat Guler (METU)08/05/2017, 17:42Dark Matter - Convenor: Carsten Rott, SKKUDirect dark matter searches are promising techniques to identify the nature of dark matter particles. A variety of experiments have been developed over the past decades, aiming to detect Weakly Interactive Massive Particles (WIMPs) via their scattering in a detector medium. Exploiting directionality would also give a proof of the galactic origin of dark matter making it possible to have a...Go to contribution page
