Linking the 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 in rare semi-leptonic -meson decays and the pr…
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…
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 . Besides, an self-int…
