Search for Dark Absorption with XENON1T
ORAL
Abstract
The XENON1T detector uses liquid xenon time projection chamber to search for nuclear recoils caused by hypothetical Weakly Interacting Massive Particles (WIMPs). With the large exposure and low electron-recoil background rate, it's also intriguing to search for dark absorption, electronic recoils produced via absorption of bosonic dark matter(dark photon, ALPs, superWIMPs), in the XENON1T detector. With the knowledge of efficiency and background, a profile likelihood analysis is used to constrain dark photon to photon kinetic mixing parameter and axion-electron coupling.
