Search for MeV-Scale Axionlike Particles and Dark Photons with PandaX-4T
Axionlike 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 440 kg·yr 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 across the range of 150 keV/c^{2} to 1 MeV/c^{2}. The improvement is particularly significant within the mass range of 150-400 keV/c^{2}, with the average factor of 3.5 compared to previous results.
