Linking the $R_{K^{(*)}}$ anomalies to the Hubble tension via a single right-handed neutrino

Wen-Feng Duan, Shao-Ping Li, Xin-Qiang Li +1

The updated measurements from the LHCb and SH0ES collaborations have respectively strengthened the deviations of the ratio $R_{K}$ in rare semi-leptonic $B$ -meson decays and the pr…

Prospects for discovering new physics in charm sector through low-energy scattering processes $e^{-} p \to e^{-} (μ^{-}) Λ_{c}$

Li-Fen Lai, Xin-Qiang Li, Xin-Shuai Yan +1

We investigate the potential for discovering new physics through the low-energy scattering processes $e^{-} p \to e^{-} (μ^{-}) Λ_{c}$ , which could be accessible in the forthcoming $e p$ scatte…

$C P$ asymmetry in the angular distributions of $τ \to K_{S} π ν_{τ}$ decays -- II: general effective field theory analysis

Feng-Zhi Chen, Xin-Qiang Li, Shi-Can Peng +2

We proceed to study the $C P$ asymmetry in the angular distributions of $τ \to K_{S} π ν_{τ}$ decays within a general effective field theory framework including four-fermion operators up t…

Simple estimate of BBN sensitivity to light freeze-in dark matter

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

We provide a simple analysis of the big-bang nucleosynthesis (BBN) sensitivity to the light dark matter (DM) generated by the thermal freeze-in mechanism. It is shown that the rati…

Baryogenesis from Hierarchical Dirac Neutrinos

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

We present here a novel and testable mechanism for leptogenesis, which is characterized by a purely thermal generation of lepton asymmetry via scalar decay. Guided by the thermal m…

New physics in the angular distribution of $B_{c}^{-} \to J / ψ (\to μ^{+} μ^{-}) τ^{-} (\to π^{-} ν_{τ}) ν ˉ_{τ}$ decay

Quan-Yi Hu, Xin-Qiang Li, Xiao-Long Mu +2

In $B_{c}^{-} \to J / ψ (\to μ^{+} μ^{-}) τ^{-} ν ˉ_{τ}$ decay, the three-momentum $p_{τ^{-}}$ cannot be determined accurately due to the decay products of $τ^{-}$ inevitably include an…
