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…
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…
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…
Type-II Seesaw Leptogenesis along the Ridge
Chengcheng Han, Zhanhong Lei, Jin Min Yang
Type-II seesaw leptogenesis is a model that integrates inflation, baryon number asymmetry, and neutrino mass simultaneously. It employs the Affleck-Dine mechanism to generate lepto…
Testing type II seesaw leptogenesis at the LHC
Chengcheng Han, Zhanhong Lei, Weihao Liao
Type II seesaw leptogenesis simultaneously explains the origin of neutrino masses, the baryon asymmetry of our universe, and the inflation. The Large Hadron Collider(LHC) provides…
Vacuum stability of the type II seesaw leptogenesis from inflation
Chengcheng Han, Sihui Huang, Zhanhong Lei
Recently it has been found that introducing a triplet Higgs to the standard model could provide a feasible leptogenesis to generate the baryon asymmetry of our universe, providing…
Constraints on cosmic-ray boosted DM in CDEX-10
Zhan-Hong Lei, Jian Tang, Bing-Long Zhang
Dark matter (DM) direct detection experiments have been setting strong limits on the DM-nucleon scattering cross section at the DM mass above a few GeV, but leave large parameter s…
