Gauge Mediation with Sequestered Supersymmetry Breaking
Satoshi Shirai, Fuminobu Takahashi, T. T. Yanagida +1
Gauge mediation models have two drawbacks, that is, the so-called μ-problem and a lack of predictability of the gravitino dark matter abundance. We show that conformal sequestering…
Determining the mass for an ultralight gravitino at LHC
K. Hamaguchi, S. Shirai, T. T. Yanagida
In supersymmetric (SUSY) models with the gravitino being the lightest SUSY particle (LSP), the SUSY breaking scale (i.e., the gravitino mass) could be determined by measuring the l…
Composite Messenger Baryon as a Cold Dark Matter
K. Hamaguchi, S. Shirai, T. T. Yanagida
Among various supersymmetric (SUSY) models, gauge-mediated SUSY breaking models with an ultra-light gravitino of mass m_{3/2} \lesssim O(10) eV are very attractive, since they are…
Determining the Mass for a Light Gravitino
K. Hamaguchi, S. Shirai, T. T. Yanagida
Gauge mediated supersymmetry breaking scenarios with an ultra-light gravitino of mass m_{3/2}=1-10 eV are very interesting, since there is no cosmological gravitino problem. We pro…
