Dark Matter Results From 54-Ton-Day Exposure of PandaX-II Experiment
II Collaboration, Xiangyi Cui, Abdusalam Abdukerim +54
We report a new search of weakly interacting massive particles (WIMPs) using the combined low background data sets in 2016 and 2017 from the PandaX-II experiment in China. The late…
PandaX-II Constraints on Spin-Dependent WIMP-Nucleon Effective Interactions
Jingkai Xia, Abdusalam Abdukerim, Xun Chen +57
We present PandaX-II constraints on candidate WIMP-nucleon effective interactions involving the nucleon or WIMP spin, including, in addition to standard axial spin-dependent (SD) s…
Constraining self-interacting dark matter with the full dataset of PandaX-II
Jijun Yang, Abdusalam Abdukerim, Wei Chen +69
Self-interacting Dark Matter (SIDM) is a leading candidate proposed to solve discrepancies between predictions of the prevailing cold dark matter theory and observations of galaxie…
Internal Calibration of the PandaX-II Detector with Radon Gaseous Sources
Wenbo Ma, Abdusalam Abdukerim, Zihao Bo +65
We have developed a low-energy electron recoil (ER) calibration method with Rn for the PandaX-II detector. Rn, emanated from natural thorium compounds, was fed into…
Exploring the dark matter inelastic frontier with 79.6 days of PandaX-II data
II Collaboration, Xun Chen, Abdusalam Abdukerim +45
We report here the results of searching for inelastic scattering of dark matter (initial and final state dark matter particles differ by a small mass splitting) with nucleon with t…
Screener3D: a Gaseous Time Projection Chamber for Ultra-low Radioactive Material Screening
Haiyan Du, Chengbo Du, Karl Giboni +8
In experiments searching for rare signals, background events from the detector itself are some of the major factors limiting search sensitivity.Screening for ultra-low radioactive…
