Cosmic Ray Positron and Electron Excess from Hidden-Fermion Dark Matter Decays
Koichi Hamaguchi, Satoshi Shirai, T. T. Yanagida
The anomalies observed in recent cosmic ray experiments seem to strongly constrain the nature of the dark matter. In this letter, we investigate a possibility of the fermionic dark…
Decaying Dark Matter Baryons in a Composite Messenger Model
Koichi Hamaguchi, Eita Nakamura, Satoshi Shirai +1
A baryonic bound state with a mass of O(100) TeV, which is composed of strongly interacting messenger quarks in the low scale gauge mediation, can naturally be the cold dark matter…
Strongly Interacting Gauge Mediation at the LHC
Koichi Hamaguchi, Eita Nakamura, Satoshi Shirai +1
Strongly interacting gauge mediation (SIGM) of supersymmetry breaking is very attractive, since it naturally predicts a light gravitino of mass $\lsim{\cal O}(10)$ eV, which causes…
