Title: New Physics Interpretations of the XENON1T Excess
Abstract: The XENON1T collaboration has observed an excess in electronic recoil events below 5 keV over the known background, which could originate from beyond-the-Standard-Model physics.
In this talk, I will review some of the theoretical interpretations of the XENON1T excess, including axions, dark photons, and other dark matter models. In particular, I will focus on the solar axion, and discuss some astrophysical constraints and inverse Primakoff in the detection. After including the keV photon produced via inverse Primakoff in the detection, the tension with the astrophysical constraints can be significantly reduced.
