Searching for Solar-Basin Axionlike-Particle Decay with XMM-Newton Blank-Sky Observations
Bo Zhang, Chi Zhang, Lei Lei +4
Axion-like particles (ALPs) bound in the solar gravitational field form the so-called ALP solar-basin. Since the two-photon decay of non-relativistic particles is approximately iso…

New Constraints on Cosmic-ray boosted Sub-GeV Dark Matter via Light Mediators
Yang Yu, Guan-Sen Wang, Bo Zhang +3
Traditional direct detection experiments lack the sensitivity to probe the sub-GeV dark matter (DM), primarily due to the low energy of the expected nuclear recoils. In this work,…

New constraints on singlet scalar dark matter model with LZ, invisible Higgs decay and gamma-ray line observations
Yang Yu, Tian-Peng Tang, Lei Feng
The singlet scalar dark matter (DM) model is a minimal extension of the Standard Model (SM). This model features only two free parameters: the singlet scalar mass and the qua…
