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…
Conformal Gauge Mediation and Light Gravitino of Mass m_{3/2} <O(10) eV
M. Ibe, Y. Nakayama, T. T. Yanagida
We discuss a class of gauge mediated supersymmetry breaking models with conformal invariance above the messenger mass scale (conformal gauge mediation). The spectrum of the supersy…
Conformal Supersymmetry Breaking and Dynamical Tuning of the Cosmological Constant
M. Ibe, Y. Nakayama, T. T. Yanagida
We propose "conformal supersymmetry breaking" models, which tightly relate the conformal breaking scale (i.e. R-symmetry breaking scale) and the supersymmetry breaking scale. The b…
