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…

Self-interacting dark matter without prejudice

Nicolás Bernal, Xiaoyong Chu, Suchita Kulkarni +1

The existence of dark matter particles that carry phenomenologically relevant self-interaction cross sections mediated by light dark sector states is considered to be severely cons…

A Practical and Consistent Parametrization of Dark Matter Self-Interactions

Xiaoyong Chu, Camilo Garcia-Cely, Hitoshi Murayama

Self-interacting dark matter has been proposed to explain the apparent mass deficit in astrophysical small-scale halos, while observations from galaxy clusters suggest that the cor…

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,…

Finite-size dark matter and its effect on small-scale structure

Xiaoyong Chu, Camilo Garcia-Cely, Hitoshi Murayama

If dark matter has a finite size that is larger than its Compton wavelength, the corresponding self-interaction cross section decreases with the velocity. We investigate the implic…
