Pseudo-scalar dark matter from a broken gauged symmetry

Junho Kang, Sarif Khan, Jongkuk Kim +1

We propose a novel model for pseudo-scalar dark matter (PSDM) by extending the Standard Model (SM) with a dark gauged $U (1)_{X}$ symmetry, but without dark charged fermions. We impos…

Baryogenesis and Dark Matter from non-thermally produced WIMPs

Giorgio Arcadi, Sarif Khan, Agnese Mariotti

We illustrate, via a simplified model, a scenario in which the baryon-asymmetry and, possibly the dark matter component of the Universe are simultaneously generated by the decay of…

WIMP-FIMP option and neutrino masses via a novel anomaly-free B-L symmetry

Sarif Khan, Hyun Min Lee

We propose a novel $U (1)_{B - L}$ model with singlet dark matter fermions composed of WIMP and FIMP, which is anomaly-free without a need for introducing right-handed neutrinos. Ferm…

Constraining dark matter from strong phase transitions in a $U (1)_{L_{I^} ¼ - L_{I ¨} }$ model: Implications for neutrino masses and muon $g - 2$

Sandhya Choubey, Sarif Khan, Marco Merchand +1

In this paper, we study a non-minimal gauged $U (1)_{L_{I^} ¼ - L_{I ¨} }$ model, where we add two complex singlet scalars, three right-handed Majorana neutrinos (RHN), and a vector-like dark…
