The dual-phase xenon time projection chamber (TPC) is a powerful technology to detect rare interactions such as scatters of dark matter particles on nuclei. In particular, the buil…
Discrimination of electronic recoils from nuclear recoils in two-phase xenon time projection chambers
LUX Collaboration, D. S. Akerib, S. Alsum +94
We present a comprehensive analysis of electronic recoil vs. nuclear recoil discrimination in liquid/gas xenon time projection chambers, using calibration data from the 2013 and 20…
Search for two neutrino double electron capture of Xe and Xe in the full exposure of the LUX detector
LUX Collaboration, D. S. Akerib, S. Alsum +96
Two-neutrino double electron capture is a process allowed in the Standard Model of Particle Physics. This rare decay has been observed in Kr, Ba and more recently in…
LUX Trigger Efficiency
