Gravity Mediation of Supersymmetry Breaking with Dynamical Metastability
K. -I. Izawa, Fuminobu Takahashi, T. T. Yanagida +1
We argue that the Polonyi problem can be avoided when our supersymmetry-breaking vacuum is surrounded by many supersymmetric vacua. We construct a dynamical class of supersymmetry-…
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…
Upperbound on Squark Masses in Gauge-Mediation Model with Light Gravitino
Junji Hisano, Minoru Nagai, Shohei Sugiyama +1
We examine stabilities of our supersymmetry-breaking false vacuum in a low-energy direct gauge mediation model of SUSY breaking. The stability required in the high-temperature earl…
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…
A Problem of the QCD Axion in Supergravity
Motoi Endo, Fuminobu Takahashi, T. T. Yanagida
This paper has been withdrawn by the authors due to a crucial error in equation 12.
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…
