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…
A Measurement of Neutralino Mass at the LHC in Light Gravitino Scenarios
Koichi Hamaguchi, Eita Nakamura, Satoshi Shirai
We consider supersymmetric (SUSY) models in which a very light gravitino is the lightest SUSY particle. Assuming that a neutralino is the next-to-lightest SUSY particle, we present…
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…
