Féeton ( Gauge Boson) Dark Matter Testable in Future Direct Detection Experiments
Yu Cheng, Jie Sheng, Tsutomu T. Yanagida
In this paper, we revisit the féeton (gauge boson of symmetry) dark matter scenario, and first point out the gauge symmetry can be a linear combination of the $…
Proposal for a Quantum Mechanical Test of Gravity at Millimeter Scale
Yu Cheng, Jiadu Lin, Jie Sheng +1
The experimental verification of the Newton law of gravity at small scales has been a longstanding challenge. Recently, torsion balance experiments have successfully measured gravi…
Detecting a Fifth-Force Gauge Boson via Superconducting Josephson Junctions
Yu Cheng, Jie Sheng, Tsutomu T. Yanagida
A new fifth force between particles carrying charges is well-motivated by the intriguing extension of the standard model. The gauge boson mediator, Féeton, also…
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…
