Solar Capture and Suppressed Annihilation of Inelastic Scalar Dark Matter

XinXin Qi, Hao Sun

Solar capture of inelastic dark matter does not by itself fix the annihilation signal. We consider a scalar low-energy model with a $B - 3 L_{τ}$ current, motivated by the high-energy r…

Thermal contact and direct detection in a broken $Z_{4}$ Majorana dark matter model

XinXin Qi, Hao Sun

We consider a broken $Z_{4}$ Majorana dark matter model in which the fermion mass is generated by a real singlet scalar. For small scalar mixing, freeze-out is dominated by $χχ\to h_…

FIMPs in a two-component dark matter model with $Z_{2} \times Z_{4}$ symmetry

XinXin Qi, Hao Sun

We investigate the FIMP-FIMP regime in a two-component dark matter model with a $Z_{2} \times Z_{4}$ symmetry, where a singlet scalar $S$ and a Majorana fermion $χ$ serve as the dark ma…

Mixed WIMP-FIMP scenario in a two-component dark matter model

XinXin Qi, Hao Sun

We consider the mixed WIMP-FIMP scenario in a two-component dark matter model with $Z_{2} \times Z_{4}$ symmetry, where a singlet scalar $S$ and a Majarano fermion $χ$ are introduced a…

Prospects for $P$ and $C P$ violation in $Λ_{c}^{+}$ decays with polarized beam at Super Tau-Charm Facility

Hong-Jian Wang, Cheng Wang, Hao Sun +3

Weak decays of the charmed baryons offer an ideal platform to study parity ( $P$ ) and charge conjugation-parity ( $C P$ ) violation in quark sector, to stringently test the Standard…

A two-component dark matter model with $Z_{2} \times Z_{4}$ symmetry

XinXin Qi, Hao Sun

We consider a two-component dark matter model with $Z_{2} \times Z_{4}$ symmetry, where a singlet scalar $S$ and a Majorana fermion $χ$ are introduced as dark matter candidates. We als…

Dark matter, leptogenesis and Z' in the B-L model

XinXin Qi, Hao Sun

We discuss the interplay between dark matter, leptogenesis and a new gauge boson $Z^{'}$ in the $B - L$ model. A fermion dark matter $χ$ carrying $U (1)_{B - L}$ charge is introduced…

Z_5 two-component dark matter in the Type-II seesaw mechanism

XinXin Qi, Hao Sun

We consider the Z5 two-component dark matter model within the framework of the Type-II seesaw mechanism. Due to the new annihilation processes related to triplets, the light compon…
