Freeze-in self-interacting dark matter in warped extra dimension

Shao-Ping Li, Xin Zhang

A classically scale-invariant scalar singlet can be a MeV-scale dark matter, with a feeble Higgs portal coupling at $O (1 0^{- 10})$ . Besides, an $O (0.1)$ self-int…

Power-aligned 2HDM: a correlative perspective on $(g - 2)_{e, μ}$

Shao-Ping Li, Xin-Qiang Li, Yuan-Yuan Li +2

With the hypothesis of minimal flavor violation, we find that there exists a power-aligned relation between the Yukawa couplings of the two scalar doublets in the two-Higgs-doublet…

Freeze-in Dirac neutrinogenesis: thermal leptonic CP asymmetry

Shao-Ping Li, Xin-Qiang Li, Xin-Shuai Yan +1

We present a freeze-in realization of the Dirac neutrinogenesis in which the decaying particle that generates the lepton-number asymmetry is in thermal equilibrium. As the right-ha…

Probing New Physics Signals with Symmetry-Restored Yukawa Textures

Shao-Ping Li, Xin-Qiang Li

We implement a symmetry violation guideline into a two-Higgs-doublet model embedded with three right-handed neutrinos, and exploit the generic Yukawa structures of the model via a…

Muon $g - 2$ in a $U (1)$ -symmetric Two-Higgs-Doublet Model

Shao-Ping Li, Xin-Qiang Li, Ya-Dong Yang

We show in this paper that, in a $U (1)$ -symmetric two-Higgs-doublet model (2HDM), the two additional neutral Higgs bosons would become nearly degenerate in the large $tan β$ regime…

$R_{D^{()}}$ , $R_{K^{()}}$ and neutrino mass in the 2HDM-III with right-handed neutrinos

Shao-Ping Li, Xin-Qiang Li, Ya-Dong Yang +1

Given that the two-Higgs-doublet model of type III (2HDM-III) has the potential to address the $R_{D^{(*)}}$ anomalies while the resolution to the $R_{K^{(*)}}$ deficits requ…
