The PandaX-4T experiment, one of the most sensitive dark matter search experiments to date, employs a two-phase liquid/gas xenon time projection chamber containing 4 tonnes of liquid xenon. The primary goals are to detect dark matter and to probe neutrino properties. Located in the Jinping Underground Laboratory in Sichuan, China, with 2400 meters of rock overburden for shielding against...
Plasmon, a collective mode of electronic excitation in solid-state detectors, provides a novel way to detect light dark matter (DM). In this work, we present the conditions of DM to produce plasmon resonance, requiring relativistic velocities for light DM, and generalize the collective excitation framework to account for relativistic DM. As a demonstration, we consider the cosmic ray boosted...
We discuss the catalysis of the primordial black holes(PBH) on the first-order electroweak phase transition(FOEWPT). We accurately studied the nucleation rate for bubbles around the PBH by solving the Einstein and bounce equations rather than applying the thin-wall approximation. We found the ordinary thin-wall approximation will overestimate the nucleation rate. For the first time, we showed...
