Searching for MeV-scale Axion-like Particles and Dark Photons with PandaX-4T
Axion-like particles (ALPs) and dark photons (DPs) are viable dark matter
particle candidates. We have searched for possible ALP/DP signals in the
PandaX-4T liquid xenon detector using 94.8 days of data. A binned likelihood
fit is constructed to search for possible mono-energetic peaks induced by the
absorption processes between ALPs/DPs and atomic electrons of xenon. A detailed
temporal model of decays associated with xenon isotopes is introduced to
constrain the number of background events. No signal excess over background
expectations is observed, and we have established the most stringent exclusion
limits for most ALP/DP masses ranging from 150 keV/$c^2$ to 1 MeV/$c^2$.
