We develop a general framework for the computation of light-portal dark matter direct detection, incorporating a consistent treatment of finite momentum trans- fer. In this framework, dark matter interacts with Standard Model matter through a light mediator, which simultaneously serves as the force carrier for dark matter self-interaction, potentially with a distinct coupling strength. The...
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....
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...
Freeze-in regime of inelastic DM with electromagnetic form factors We investigate the freeze-in production of inelastic dark matter (DM) consisting of two nearly degenerate fermions coupled to the Standard Model through electromagnetic form factors: electric and magnetic dipole moments (dimension 5), and anopole moment and charge radius (dimension 6). We investigate low reheating temperature...
