Constraints on ultraheavy dark matter from the CDEX-10 experiment at the China Jinping Underground Laboratory
Y. F. Wang, L. T. Yang, Q. Yue +83
We report a search for ultraheavy dark matter (UHDM) with the CDEX-10 experiment at the China Jinping Underground Laboratory. Using a Monte Carlo framework that incorporates Earth…
Pulse shape simulation for the reduced charge collection layer in p-type high-purity germanium detectors
P. Zhang, W. Dai, Q. Zhang +8
-type high-purity germanium (HPGe) detectors are widely used across many scientific domains, and current data analysis methods have served well in many use cases. However, appli…
First search for light fermionic dark matter absorption on electrons using germanium detector in CDEX-10 experiment
J. X. Liu, L. T. Yang, Q. Yue +83
We present the first results of the search for sub-MeV fermionic dark matter absorbed by electron targets of germanium using the 205.4~kgday data collected by the CDEX-10 ex…
Constraints on dark matter boosted by supernova shock within the effective field theory framework from the CDEX-10 experiment
J. Z. Wang, L. T. Yang, Q. Yue +83
Supernova shocks can boost dark matter (DM) particles to high, yet nonrelativistic, velocities, providing a suitable mechanism for analysis within the framework of the nonrelativis…
Measurement of cosmic-ray muon flux at CJPL-II
P. Zhang, H. Ma, W. Dai +5
In China Jinping Underground Laboratory (CJPL), the deepest and largest underground laboratory globally, the cosmic-ray muon flux is significantly reduced due to the substantial sh…
In-situ environmental radiation background measurement in the second phase of CJPL
P. Zhang, Z. Zeng, J. Cheng +1
China Jinping Underground Laboratory (CJPL), the deepest and largest underground laboratory worldwide, provides a low radiation background environment, which is necessary to fronti…
