Scalar Dark Matter Candidates -- Revisited
Céline Bœhm, Xiaoyong Chu, Jui-Lin Kuo +1
We revisit the possibility of light scalar dark matter, in the MeV to GeV mass bracket and coupled to electrons through fermion or vector mediators, in light of significant experim…
Dark sector-photon interactions in proton-beam experiments
Xiaoyong Chu, Jui-Lin Kuo, Josef Pradler
We consider electromagnetically neutral dark states that couple to the photon through higher dimensional effective operators, such as electric and magnetic dipole moment, anapole m…
Stellar probes of dark sector-photon interactions
Xiaoyong Chu, Jui-Lin Kuo, Josef Pradler +1
Electromagnetically neutral dark sector particles may directly couple to the photon through higher dimensional effective operators. Considering electric and magnetic dipole moment,…
The impact of EDGES 21-cm data on dark matter interactions
Kingman Cheung, Jui-Lin Kuo, Kin-Wang Ng +1
The recently announced results on the 21-cm absorption spectrum by the EDGES experiment can place very stringent limits on dark matter annihilation cross-sections. We properly take…
Decaying warm dark matter and structure formation
Jui-Lin Kuo, Massimiliano Lattanzi, Kingman Cheung +1
We examine the cosmology of warm dark matter (WDM), both stable and decaying, from the point of view of structure formation. We compare the matter power spectrum associated to WDM…
