CP asymmetries of $t \to c γ$ and $t \to c g$ decays in the aligned two-Higgs-doublet model

Fang-Min Cai, Rui-Lin Fan, Xin-Qiang Li +1

We study the CP asymmetries of the rare top-quark decays $t \to c γ$ and $t \to c g$ in the aligned two-Higgs-doublet model (A2HDM), which is generically characterized by new source…

Study of the $B^{-} \to K^{-} η η_{c}$ decay due to the $D D ˉ$ bound state

Xin-Qiang Li, Li-Juan Liu, En Wang +1

We study the $B^{-} \to K^{-} η η_{c}$ decay by taking into account the $S$ -wave contributions from the pseudoscalar meson-pseudoscalar meson interactions within the unitary coupled-chann…

$B_{c}^{-} \to J / ψ (\to μ^{+} μ^{-}) τ^{-} (\to π^{-} ν_{τ}, ρ^{-} ν_{τ}, ℓ^{-} ν ˉ_{ℓ} ν_{τ}) ν ˉ_{τ}$ decays with visible final-state kinematics

Xin-Qiang Li, Xin Xu, Ya-Dong Yang +1

The semitauonic $B_{c}^{-} \to J / ψ τ^{-} ν ˉ_{τ}$ decay is optimal to scrutinize possible new physics effects in $b \to c τ^{-} ν ˉ_{τ}$ transitions as indicated by the current data on $R(D^…

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…

$C P$ asymmetry in the angular distribution of $τ \to K_{S} π ν_{τ}$ decays

Feng-Zhi Chen, Xin-Qiang Li, Ya-Dong Yang

In this work, we study the $C P$ asymmetry in the angular distribution of $τ \to K_{S} π ν_{τ}$ decays, taking into account the known $C P$ violation in $K^{0} - K ˉ^{0}$ mixing. It is pointe…

CP asymmetry in $τ \to K_{S} π ν_{τ}$ decays within the Standard Model and beyond

Feng-Zhi Chen, Xin-Qiang Li, Ya-Dong Yang +1

Motivated by the $2.8 σ$ discrepancy observed between the BaBar measurement and the Standard Model prediction of the CP asymmetry in $τ \to K_{S} π ν_{τ}$ decays, as well as the prospects…

$B_{s (d)} - B ˉ_{s (d)}$ Mixing and $B_{s} \to μ^{+} μ^{-}$ Decay in the NMSSM with the Flavour Expansion Theorem

Quan-Yi Hu, Xin-Qiang Li, Ya-Dong Yang +1

In this paper, motivated by the observation that the Standard Model predictions are now above the experimental data for the mass difference $Δ M_{s (d)}$ , we perform a detailed study…

$R_{D^{()}}$ , $R_{K^{()}}$ 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…
