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…
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…
Correlation length of the angular mode for an approximate symmetry during inflation
Chengcheng Han
It is known that a light scalar field obtains fluctuations in the de Sitter inflationary background. Such fluctuations could provide an initial condition for baryogenesis through t…
Type II Seesaw Leptogenesis
Neil D. Barrie, Chengcheng Han, Hitoshi Murayama
The Type II Seesaw Mechanism provides a minimal framework to explain the neutrino masses involving the introduction of a single triplet Higgs to the Standard Model. However, this s…
