Low-Scale Leptogenesis from Resonant Thermal Lepton Flavour Coherences
Shao-Ping Li, Apostolos Pilaftsis
Resonant heavy-neutrino mixing and sterile neutrino oscillations are two prominent mechanisms to realize low-scale leptogenesis, with singlet neutrino masses below TeV energies tha…
A collider test of nano-Hertz gravitational waves from pulsar timing arrays
Shao-Ping Li, Ke-Pan Xie
A cosmic first-order phase transition (FOPT) occurring at MeV-scale provides an attractive explanation for the nano-Hertz gravitational wave (GW) background indicated by the recent…
Dark matter freeze-in via a light fermion mediator: forbidden decay and scattering
Shao-Ping Li
The connection between a hidden nonthermal sector and a thermal plasma can be established by a light thermal fermion mediator. When the fermion mediator is much lighter than the hi…
Scattering versus Forbidden Decay in Dark Matter Freeze-in
Shao-Ping Li
It is generically believed that the two-body scattering is suppressed by higher-order weak couplings with respect to the two-body decay. We show that this does not always hold when…
Neutrino Magnetic Moments Meet Precision Measurements
Shao-Ping Li, Xun-Jie Xu
In the early universe, Dirac neutrino magnetic moments due to their chirality-flipping nature could lead to thermal production of right-handed neutrinos, which would make a signifi…
Scotogenic Dirac neutrino mass models embedded with leptoquarks: one pathway to address the flavor anomalies and the neutrino masses together
Shao-Ping Li, Xin-Qiang Li, Xin-Shuai Yan +1
If the leptoquarks proposed to account for the intriguing anomalies observed in the -meson decays, and , as well as in the anomalous magnetic mo…
Effective neutrino number shift from keV-vacuum neutrinophilic 2HDM
Shao-Ping Li, Xin-Qiang Li, Xin-Shuai Yan +1
If the Dirac neutrino masses are generated by a new scalar doublet with a vacuum at keV order, there would be rare hope to probe the framework in low-energy flavor physics, such as…
Next-to-tribimaximal mixing against CP violation and baryon asymmetry signs
Shao-Ping Li, Yuan-Yuan-Li, Xin-Shuai Yan +1
Four next-to-tribimaximal (NTBM) mixing patterns are widely considered as the feasible candidates for the observed leptonic mixing structure. With the recent measurements from T2K,…
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…
Power-aligned 2HDM: a correlative perspective on
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 in a -symmetric Two-Higgs-Doublet Model
Shao-Ping Li, Xin-Qiang Li, Ya-Dong Yang
We show in this paper that, in a -symmetric two-Higgs-doublet model (2HDM), the two additional neutral Higgs bosons would become nearly degenerate in the large regime…

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 anomalies while the resolution to the deficits requ…
