High-energy Cosmic-Ray Positrons from Hidden-Gauge-Boson Dark Matter
Chuan-Ren Chen, Fuminobu Takahashi, T. T. Yanagida
We provide a scenario in which a hidden U(1) gauge boson constitutes dark matter of the Universe and decays into the standard-model particles through a kinetic mixing with an $U(1)…
