Right-Handed Neutrino Production by an Axion-like Inflaton: Implications for Leptogenesis
Weiyi Deng, Chengcheng Han, Wuzhou Yin +1
We study heavy right-handed neutrino production induced by a derivative coupling to an axion-like inflaton and its implications for non-thermal leptogenesis. We develop a unified t…
Line-of-sight magnetic-field propagation effects on axion-like particle constraints from GRB 221009A
Chengcheng Han, Zhanhong Lei, Jiajie Yang +1
High-energy photons from GRB 221009A provide a powerful opportunity to probe axion-like particles (ALPs) through photon-ALP oscillations in cosmic magnetic fields. We revisit the A…
Curvature Perturbations from Higgs Modulated Reheating
Weiyi Deng, Chengcheng Han, Zhanhong Lei +1
In this work we investigate curvature perturbations and non-Gaussianity arising from Higgs modulated reheating in the early Universe. We employ three different methods -- the perio…
Probing Type II Seesaw Leptogenesis Through Lepton Flavor Violation
Chengcheng Han, Yijun Han, Sihui Huang +1
Lepton flavor violation (LFV) offers a powerful probe of physics beyond the Standard Model, particularly in models addressing neutrino masses and the baryon asymmetry of the univer…
Hybrid Type-II and Type-III seesaw model for the muon anomaly
Lei Cai, Chengcheng Han, Shi-Ping He +1
In this work we investigate the muon anomalous magnetic dipole moment in a model that extends the Standard Model with a scalar triplet and a lepton triplet. Different from pr…
Probing Non-Thermal Gravitinos Through Large-Scale Structure Observations
Weiyi Deng, Liyuan Guo, Chengcheng Han +1
We investigate the effects of non-thermally produced dark matter on large-scale structure formation, focusing on the gravitino dark matter. Our analysis shows that large-scale stru…
