On November 25th, CDEX (China Dark matter EXperiment) collaboration, led by Tsinghua University, published an article entitled “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” in Physical Review Letters (Phys. Rev. Lett. 123, 221301, 2019). In this work, the 90% C.L. allowed regions implied by the DAMA/LIBRA and CoGeNT AM-based analysis are excluded at >99.99% and 98% confidence level (C.L.), respectively. These results correspond to the best sensitivity at mχ<6 GeV among the annual modulation measurements of weakly interacting massive particles (WIMPs, denoted as χ) to date.
