Heavy singlet fermionic dark matter with $Z_{4}$ symmetry

XinXin Qi, Hao Sun

We revisited the singlet fermionic dark matter model in this work, where a Majorana fermion $I ¨ $ carrying $Z_{4}$ charge is assumed as the DM candidate. A new singlet scalar $S_{0}$ wi…

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…

Finding the stable mechanism of ring solitons in two-dimensional Fermi superfluids

Hao-Xuan Sun, Liu-Yang Cheng, Shi-Guo Peng +2

We theoretically investigate the stable mechanism of a ring soliton in two-dimensional Fermi superfluids by solving the Bogoliubov-de Gennes equations and their time-dependent coun…

Chains of rotating boson stars with quartic or sextic self-interaction

Hao-Ran Sun, Jing-Kang Bin, Li Zhao

This paper investigates chains of rotating boson stars (BSs) within Einstein gravity coupled to a complex scalar field. The model incorporates quartic or sextic self-interactions i…

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 $I ¨ $ are introduced…

Prospects for $P$ and $C P$ violation in $I^_{c}^{+}$ 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…
