It is assumed that heavy dark matter particles (HDMs) with the mass of O(TeV) are captured by the Sun. HDMs decay to relativistic lighter dark matter particles (LDMs). These high energy LDMs can be measured by km$^3$ neutrino telescopes, like the IceCube detector. A $Z^{prime}$ portal dark matter model is taken for LDMs to interact with nuclei via a neutral current. With the different lifetimes of decay of HDMs and Z$^{prime}$ masses, the distributions and numbers of expected LDMs and neutrinos were evaluated at IceCube in the energy range between 1 TeV and 200 TeV in this work. To evaluate the capability of measurement of these LDMs from the sun core at IceCube, two observation results were assumed: one is the observation is consistent with the number of expect neutrinos; the other is no events are observed in this measurement. Based on these two assumptions, the upper limits for LDM fluxes were computed at 90% C.L.. With $m_{Z^{prime}} lesssim$ 400 GeV and $tau_{phi} lesssim 10^{23}$ s, finally, it is revealed that these LDMs could be measured in the energy range between O(1TeV) and O(100TeV) at IceCube.
We present results from an analysis looking for dark matter annihilation in the Sun with the IceCube neutrino telescope. Gravitationally trapped dark matter in the Suns core can annihilate into Standard Model particles making the Sun a source of GeV
Weakly interacting massive particles (WIMPs) can be gravitationally captured by the Sun and trapped in its core. The annihilation of those WIMPs into Standard Model particles produces a spectrum of neutrinos whose energy distribution is related to th
We have performed a search for muon neutrinos from dark matter annihilation in the center of the Sun with the 79-string configuration of the IceCube neutrino telescope. For the first time, the DeepCore sub-array is included in the analysis, lowering
A search for an excess of muon-neutrinos from dark matter annihilations in the Sun has been performed with the AMANDA-II neutrino telescope using data collected in 812 days of livetime between 2001 and 2006 and 149 days of livetime collected with the
We present a flavor and energy inference analysis for each high-energy neutrino event observed by the IceCube observatory during six years of data taking. Our goal is to obtain, for the first time, an estimate of the posterior probability distributio
