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…
Gravitational Waves as a Probe of the Gravitino Mass
Fuminobu Takahashi, T. T. Yanagida, Kazuya Yonekura
If gaugino condensations occur in the early universe, domain walls are produced as a result of the spontaneous breaking of a discrete R symmetry. Those domain walls eventually anni…
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This paper has been withdrawn by the authors due to a crucial error in equation 12.
Dark Matter in Gauge Mediated Supersymmetry Breaking using Metastable Vacua
Motoi Endo, Fuminobu Takahashi
We point out that, in a class of gauge mediation models using metastable supersymmetry breaking vacua, the minimum of the supersymmetry breaking field in the early universe is dyna…
Entropy production by Q-ball decay for diluting long-lived charged particles
Shinta Kasuya, Fuminobu Takahashi
The cosmic abundance of a long-lived charged particle such as a stau is tightly constrained by the catalyzed big bang nucleosynthesis. One of the ways to evade the constraints is t…
