Description

The Large Underground Xenon (LUX) experiment is a 350 kg liquid xenon time projection chamber (TPC) designed to directly detect galactic dark matter. Xenon detectors present suitable features to detect dark matter candidates other than WIMPs, such as axions, because of the extremely low radioactivity background for electronic recoils they can provide. LUX can probe both axions coming from the Sun and axion-like particles (ALPs) moving within our Galaxy, thanks to their coupling to electrons, via the so called axio-electric effect. Although theoretically well motivated, axions have yet to be detected experimentally. We present a theoretical introduction on the two axion models: the solar axions and the galactic ALPs. An overview on what the axion signal looks like in LUX follows. The status of the axion analysis on LUX Run 3 data will be presented, together with a description of the relevant LUX background.
