Cosmological Collider Signatures from Right-Handed Neutrino Loop
Jingtao You, Linghao Song, Chengcheng Han +3
We study cosmological collider (CC) signatures generated by right-handed neutrino loops in the setup of inflation combined with the neutrino seesaw mechanism. We formulate the infl…
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…
Freeze-in bino dark matter in high scale supersymmetry
Chengcheng Han, Peiwen Wu, Jin Min Yang +1
We explore a scenario of high scale supersymmetry where all supersymmetric particles except gauginos stay at a high energy scale which is much larger than the reheat…
Self-interacting dark matter implied by nano-Hertz gravitational waves
Chengcheng Han, Ke-Pan Xie, Jin Min Yang +1
The self-interacting dark matter (SIDM) paradigm offers a potential solution to the small-scale structure problems faced by collision-less cold dark matter. This framework incorpor…
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…
QCD axion dark matter and the cosmic dipole problem
Chengcheng Han
There is increasing evidence suggesting a discrepancy between the cosmic dipole observed in the number count of distant galaxies and the one derived from the cosmic microwave backg…
