Dark matter searches (direct and indirect)

Prospects for dark matter discovery with inelastic transitions of xenon

Abstract content

Dark matter can excite the xenon isotopes 129Xe and 131Xe through a spin dependent interaction. The excited isotopes quickly decay giving a 40 keV and 80 keV photon, respectively. This signal is very distinct from the usual signal from elastically scattering dark matter and, if discovered, would provide clear evidence against the usual spin independent interaction. I discuss the prospects of discovering this inelastic signal with up-coming tonne-scale two-phase xenon direct detection experiments.
