Tritiated methane reduction in the PandaX-4T experiment via purge and cryogenic distillation processes
Shuaijie Li, Zhou Wang, Xiangyi Cui +7
Tritium from tritiated methane (CHT) calibration is a significant impurity that restricts the sensitivity of the PandaX-4T dark matter detection experiment in the low-energy re…
Measurement of two-neutrino double electron capture half-life of Xe with PandaX-4T
PandaX Collaboration, Zihao Bo, Wei Chen +99
Detailed studies of two-neutrino double electron capture (2DEC) is a crucial step towards searching for the neutrino-less mode to explore the Majorana nature of neutrinos. We h…
Search for Solar Boosted Dark Matter Particles at the PandaX-4T Experiment
Guofang Shen, Zihao Bo, Wei Chen +100
We present a novel constraint on light dark matter utilizing tonneyear of data acquired from the PandaX-4T dual-phase xenon time projection chamber. This constraint i…
Search for Double Beta Decay of Xe to the Excited State of Ba with PandaX-4T
PandaX Collaboration, Lingyin Luo, Zihao Bo +98
We perform a search of double beta decay of Xe to the excited state, , of Ba (2-0), using the dual-phase xenon detector of PandaX-4T with the f…
Search for MeV-Scale Axionlike Particles and Dark Photons with PandaX-4T
PandaX Collaboration, Tao Li, Zihao Bo +98
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 us…
Position reconstruction and surface background model for the PandaX-4T detector
Zhicheng Qian, Linhui Gu, Chen Cheng +100
We report the position reconstruction methods and surface background model for the PandaX-4T dark matter direct search experiment. This work develops two position reconstruction al…
