Right-Handed Neutrino Dark Matter with Forbidden Annihilation
Yu Cheng, Shao-Feng Ge, Jie Sheng +1
The seesaw mechanism with three right-handed neutrinos has one as a well-motivated dark matter candidate if stable and the other two can explain baryon asymmetry via the thermal le…
Collider search of light dark matter model with dark sector decay
Yu Cheng, Wei Liao, Qi-Shu Yan
We explore the possibility that the dark matter relic density is not produced by thermal mechanism directly, but by the decay of other heavier dark sector particles which on the ot…
Gauge invariance of the vector meson mass in the Coleman-Weinberg model
Haojie Shen, Yu Cheng, Wei Liao
We revisit the problem of the gauge invariance in the Coleman-Weinberg model in which a gauge symmetry is driven spontaneously broken by radiative corrections. It was notice…
Light dark matter from dark sector decay
Yu Cheng, Wei Liao
We study the possibility that light dark matter can be produced with right relic density by the decay of other dark sector particles. We study this possibility in a model with righ…
Fate of false vacuum in singlet-doublet fermion extension model with RG improved effective action
Yu Cheng, Wei Liao
We study the effective potential and the Renormalization Group(RG) improvement to the effective potential of Higgs boson in a singlet-doublet fermion dark matter extension of the S…
