摘要

With the support by the National Natural Science Foundation of China and the National Key Research and Development Program of China,the CDEX collaboration led by Yue Qian (岳骞) from Tsinghua University reported the most stringent limits on spin-independent WIMP-nucleon cross sections for a WIMP mass of 4-5 GeV/c2 with the lowest exclusion of 8 × 10-42 cm2 using Point Contact Germanium detectors directly immersed into liquid nitrogen (LN2).The results were published in Physical Review Letters (2018,120:241301).
