“…The physics analysis threshold is 160 eVee where the combined efficiency (including the trigger efficiency and the efficiency for pulse shape discrimination) is 4.5%. The characteristic K-shell X-ray peaks from internal cosmogenic radionuclides like 68 Ge, 68 Ga, 65 Zn, 55 Fe, 54 Mn and 49 V are fitted and subtracted from the spectrum, as shown in Fig. 3(a).…”

“…The limits set by former phenomenological studies using XENON-1T data and the blazar boosting effect are also shown. The exclusion region from CDEX-10 using CR acceleration (CRDM) [29], and the published limits un-der the SHM scenario from CDEX-10 Migdal effect (ME) analysis [51],CDMSlite ME analysis [65], DarkSide-50 ME analysis [66], EDELWEISS-Surface [67], and X-ray Quantum Calorimeter experiment (XQC) [68,69] are also superimposed. The result derived from the blazar TXS 0506+56 excludes DM-nucleon elastic scattering cross sections from 4.6 × 10 −33 cm 2 to 1 × 10 −26 cm 2 for DM masses from 10 keV to 1 GeV, while the result derived from BL Lacertae excludes DM-nucleon elastic scattering cross sections from 2.4 × 10 −34 cm 2 to 1 × 10 −26 cm 2 for DM mass from 10 keV to 1 GeV.…”

We report new constraints on light dark matter (DM) boosted by blazars using the 205.4 kg day data from the CDEX-10 experiment located at the China Jinping Underground Laboratory. Two representative blazars, TXS 0506+56 and BL Lacertae are studied. The results derived from TXS 0506+56 exclude DM-nucleon elastic scattering cross sections from 4.6 × 10 −33 cm 2 to 1 × 10 −26 cm 2 for DM masses between 10 keV and 1 GeV, and the results derived from BL Lacertae exclude DMnucleon elastic scattering cross sections from 2.4 × 10 −34 cm 2 to 1 × 10 −26 cm 2 for the same range of DM masses. The constraints correspond to the best sensitivities among solid-state detector experiments in the sub-MeV mass range.
