The China Dark Matter Experiment (CDEX) pursues direct searches of light dark matter particles and neutrinoless double beta decay at the China Jinping Underground Laboratory (CJPL), which is the deepest operating laboratory for astroparticle research.
The CDEX employs germanium semi-conductor detector which has low energy threshold and excellent energy resolution. We report the latest novel...
PandaX experiment uses xenon as target to detect weak and rare physics signals, including dark matter and neutrinos. We are running a new generation detector with 4-ton xenon in the sensitive volume, PandaX-4T. The commissioning run data has pushed the constraints on WIMP-nucleon scattering cross section to a new level. In this talk, I will give an overview of PandaX-4T latest results on dark...
In this talk, I will talk about the production of sub-GeV DM from the cosmic ray collision with the atmosphere and the prospects in direct detection. I will highlight the importance of quasi-elastic scattering in the earth-stopping effect.
Motivated by the collisionless cold dark matter small scale structure problem, we propose an asymmetric dark matter model where dark matter particle interact with each other via a massive dark gauge boson. This model easily avoid the strong limits from cosmic microwave background (CMB) observation, and have a large parameter space to be consistent with small scale structure data. We focus on a...
We explore the potential of precision cosmological data to study non-minimal dark sectors by updating the cosmological constraint on the mirror twin Higgs model (MTH). The MTH model addresses the Higgs little hierarchy problem by introducing dark sector particles. In the early Universe, the mirror baryon and mirror radiation behave as dark matter and dark radiation, and their presence modifies...
