We propose DREAMuS (Dark matter REsearch with Advanced Muon Source), a new fixed-target experiment at the High-Intensity Heavy-Ion Accelerator Facility (HIAF) in China, dedicated to searching for muon-philic dark matter. Unlike traditional electron-beam experiments, DREAMuS utilizes a GeV-scale muon beam to explore dark sectors that preferentially couple to the second generation of leptons....

We report the first constraints on the light fermionic dark matter (DM) absorption on nuclear targets via magnetic dipole-based interaction, using the full 589.3 kg·day exposure collected with the CDEX-10 experiment at the China Jinping Underground Laboratory. In this work, we present a newly acquired 139.7 kg·day dataset from the C10A detector. By applying a new time-interval analysis method...

We determine the future sensitivity of the TRIDENT neutrino telescope to dark matter annihilation in the Galactic Centre. By applying the full detector design we show that TRIDENT will probe annihilation rates down to $\langle\sigma v\rangle\approx5\times10^{-27}\,{\rm cm}^3\,{\rm s}^{-1}$ for a $10\,{\rm TeV}$ dark matter, which is below the thermal freeze-out benchmark. The analysis is...

The axion-like particles $a$ can be produced in the Sun via the process of $p + D \to {}^3{\rm He} +a$, with mass up to 5.5 MeV. The photons in the subsequent decay $a \to \gamma\gamma$ can deviate significantly from the Sun, or even from roughly the opposite direction of the Sun. The nontrivial angular and spectral distributions of such photons enable us new methods to detect the {\it lights...

Majoron ($J$) is a feebly-interacting axion-like particle that can realize type-I seesaw mechanism, which also leads to flavor violating processes (FVP). We revisit prospects of sub-GeV majoron at intensity frontier experiments. We show that FVP allow to probe the majoron mass region \sim 100 MeV to 1 GeV, complementary to astrophysical bounds and dedicated experiments probing FVP. We also...
