Özet

We report the first results of a light weakly interacting massive particles (WIMPs) search from the CDEX-10 experiment with a 10 kg germanium detector array immersed in liquid nitrogen at the China Jinping Underground Laboratory with a physics data size of 102.8 kg day. At an analysis threshold of 160 eVee, improved limits of 8 x 10(-42) and 3 x 10(-36) cm(2) at a 90% confidence level on spin-independent and spin-dependent WIMP-nucleon cross sections, respectively, at a WIMP mass (m(chi)) of 5 GeV/c(2) are achieved. The lower reach of m(chi) is extended to 2 GeV/c(2).
