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. © 2025 Institute of Physics.

Supernova shocks can boost dark matter (DM) particles to high, yet nonrelativistic, velocities, providing a suitable mechanism for analysis within the framework of the nonrelativistic effective field theory (NREFT). These accelerated DM sources extend the experimental ability to scan the parameter space of light DM into the sub-GeV region. In this study, we specifically analyze DM accelerated by the Monogem Ring supernova remnant, whose age (∼68000 yr) and distance to Earth (∼300 parsec) are strategically matched to enable detection with current terrestrial detectors. Utilizing the 205.4 kg · day data obtained from the CDEX-10 experiment at the China Jinping Underground Laboratory, we derive new constraints on boosted DM within the NREFT framework. The NREFT coupling constant exclusion regions now penetrate the sub-GeV mass range, with optimal sensitivity achieved for operators O3, O6, O15 in the 0.4–0.6 GeV mass range. © (2025), (American Physical Society).

Dark matter (DM) is a major constituent of the Universe. However, no definite evidence of DM particles (denoted as “χ”) has been found in DM direct detection (DD) experiments to date. There is a novel concept of detecting χ from evaporating primordial black holes (PBHs). We search for χ emitted from PBHs by investigating their interaction with target electrons. The examined PBH masses range from 1 × 1015 to 7 × 1016 g under the current limits of PBH abundance fPBH. Using 205.4 kg·day data obtained from the CDEX-10 experiment conducted in the China Jinping Underground Laboratory, we exclude the χ-electron (χ-e) elastic-scattering cross section σχ ∼ 5 × 10−29 cm2 for χ with a mass mχ ≲ 0.1 keV from our results. With the higher radiation background but lower energy threshold (160 eV), CDEX-10 fills a part of the gap in the previous work. If (mχ,σχ) can be determined in the future, DD experiments are expected to impose strong constraints on fPBH for large MPBHs. © Science China Press 2024.
