Novel light dark matter signals in xenon direct detection experiments
Direct detection experiments that utilise xenon have proven to be most sensitive for heavy (>5 GeV) dark matter particles. In this talk, I'll explore signals that allow xenon experiments to probe the dark matter - nucleon cross section for dark matter particles down to ~100 MeV. These signals arise from electron or photon emission from the xenon atom after a collision with a light dark matter particle. This talk is based on arXiv:1702.04730 and arXiv:1711.09906.
