Thermal Relic Right-Handed Neutrino Dark Matter
Yu Cheng, Jie Sheng, Tsutomu T. Yanagida
It is known that two heavy Majorana right-handed neutrinos are sufficient to generate the baryon asymmetry in the present universe. Thus, it is interesting to identify the third ri…

Féeton ( Gauge Boson) Dark Matter for the 511-keV Gamma-Ray Excess and the Prediction of Low-energy Neutrino Flux
Yu Cheng, Weikang Lin, Jie Sheng +1
The féeton is the gauge boson of the gauge theory. If the gauge coupling constant is extremely small, it becomes a candidate for dark matter. We show that its decay to…

Dark Matter Annihilation via Breit-Wigner Enhancement with Heavier Mediator
Yu Cheng, Shao-Feng Ge, Jie Sheng +1
We propose a new scenario that both the dark matter freeze-out in the early Universe and its possible annihilation for indirect detection around a supermassive black hole are enhan…
