Experimental Limits on Solar Reflected Dark Matter with a New Approach on Accelerated-Dark-Matter-Electron Analysis in Semiconductors

Z. Y. Zhang, L. T. Yang, Q. Yue, K. Kang et autres

Recently a dark matter-electron (DM-electron) paradigm has drawn much attention. Models beyond the standard halo model describing DM accelerated by high energy celestial bodies are under intense examination as well. In this Letter, a velocity components analysis (VCA) method dedicated to swift …

Identification of single-pixel incomplete charge collection events by using cathode waveform in pixelated CdZnTe detectors

Jian Yang, Yiming Li, Yang Tian, L. Xu et autres

Common grid can steer the electron cloud toward anode pixels to improve the charge collection efficiency in pixelated CdZnTe detectors. Due to insufficient steering and the absence of pixels on the outside of the edge pixels, the whole electron cloud cannot be …

Search for Light Weakly-Interacting-Massive-Particle Dark Matter by Annual Modulation Analysis with a Point-Contact Germanium Detector at the China Jinping Underground Laboratory

L. T. Yang, H. B. Li, Qian Yue, Hao Ma et autres

We present results on light weakly interacting massive particle (WIMP) searches with annual modulation (AM) analysis on data from a 1-kg mass p-type point-contact germanium detector of the CDEX-1B experiment at the China Jinping Underground Laboratory. Datasets with a total live time …

Constraints on Spin-Independent Nucleus Scattering with sub-GeV Weakly Interacting Massive Particle Dark Matter from the CDEX-1B Experiment at the China Jinping Underground Laboratory

Ziyi Liu, Qian Yue, L. T. Yang, K. Kang et autres

We report results on the searches of weakly interacting massive particles (WIMPs) with sub-GeV masses (${m}_{\ensuremath{\chi}}$) via WIMP-nucleus spin-independent scattering with Migdal effect incorporated. Analysis on time-integrated (TI) and annual modulation (AM) effects on CDEX-1B data are performed, with 737.1 kg day …

Limits on Spin-Independent Couplings of WIMP Dark Matter with a p -Type Point-Contact Germanium Detector

H. B. Li, Haolong Liao, S. T. Lin, S. K. Liu et autres

We report new limits on a spin-independent weakly interacting massive particle (WIMP)-nucleon interaction cross section using 39.5 kg days of data taken with a p-type point-contact germanium detector of 840 g fiducial mass at the Kuo-Sheng Reactor Neutrino Laboratory. Crucial to this …

Simulation and Measurement of Quenching and Channeling Effects in CsI(Tl) for Dark Matter Search

Jun Hee Lee, H. Bhang, Junho H. Choi, Woon Gu Kang et autres

In order to understand the scintillation characteristics of nuclear recoil events in CsI(Tl) crystals and for application to the analysis of Dark Matter (DM) searches, we study quenching and channeling effects with simulations of recoil ion motion in CsI(Tl) and experiments using …
