Description

XENON1T is the world’s largest dual-phase xenon time-projection chamber, searching for dark matter via the nuclear recoils caused by interactions of weakly interacting massive particles (WIMPs) with xenon nucleons. Here a search for the inelastic WIMP-nucleus scattering is presented, whereby the interaction causes a transition to a low-lying excited nuclear state of either ¹²⁹Xe or ¹³¹Xe. Unlike elastic scattering, inelastic scattering is inherently spin-dependent and so this channel of analysis can give a direct handle on the spin-dependent nature of the interaction.
