摘　　要：We search for nuclear recoil signals of dark matter(DM)models with a light mediator using data taken from a p-type point-contact germanium detector of the CDEX-10 experiment at the China Jinping Underground Laboratory.The 90%confidence level upper limits on the DM-nucleon interaction cross section from 205.4 kg-day exposure data are derived,excluding the new parameter space in 2−3 GeV DM mass when the mediator mass is comparable to or lower than the typical momentum transfer.We further interpret our results to constrain a specific self-interacting DM model with a light mediator coupling to the photon through kinetic mixing and set experimental limits on the model parameter region favored by astrophysical observations.
