| 摘要: | The installation of DeepCore array significantly lowers IceCube\'s energy threshold to about 10 GeV and enhances the sensitivity of detecting neutrinos from annihilations and decays of light dark matter. To match this experimental development, we discuss decays of the event rate in DeepCore array due to neutrino flux produced by annihilations and galactic dark matter. This event rate is calculated with a 10 GeV threshold energy, which is smaller than the threshold energy taken in previous works. Taking into account the background event rate due to the atmospheric neutrino flux, we evaluate the sensitivity of DeepCore array for probing dark matter annihilation cross section and decay time. We compare our results with corresponding constraints derived from observations of WMAP, ACT and Fermi-LAT. |
