IceCube at the frontier of macroscopic dark matter direct detection

A bstract For a class of macroscopic dark matter models, inelastic scattering off nucleus can generate electromagnetic signatures with GeV-scale energy. The IceCube detector, its kilometer-scale size, is ideal for directly detecting such scattering. Based on the slow particle trigger DeepCore we perform detailed signal and background simulation to estimate discovery potential. order 1 GeV deposited energy in each interaction, find that probe masses up one gram.
