Description

The decay of asymmetric dark matter (ADM) leads to possible neutrino signatures with an asymmetry of neutrinos and antineutrinos. In the high-energy regime, the Glashow resonant interaction $\bar{\nu}_e+e^- \rightarrow W^-$ is the only way to differentiate the antineutrino contribution in the diffuse astrophysical high-energy neutrino flux experimentally, which provides a possibility to probe heavy ADM. In this talk, I will discuss the neutrino signal from ADM decay, the constraints with the current IceCube observation of Glashow resonance, and the projected sensitivities with the next-generation neutrino telescopes.
