Dark Z-mediated dark matter with verifiable exotic scalars
Chuan-Ren Chen, Cheng-Wei Chiang, Leon M. G. de la Vega
In this work, we study a dark matter scenario where a dark Z boson possessing mass mixing with the SM Z boson couples to the DM candidate and serves as the portal to the SM. The UV…
Decaying Hidden Gauge Boson and the PAMELA and ATIC/PPB-BETS Anomalies
Chuan-Ren Chen, Mihoko M. Nojiri, Fuminobu Takahashi +1
We show that the PAMELA anomaly in the positron fraction as well as the ATIC/PPB-BETS excesses in the e^- + e^+ flux are simultaneously explained in our scenario that a hidden U(1)…
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)…
