Metastable Vacua and Complex Deformations
We use the non-normalizable complex deformations to describe the stringy realizations of the metastable vacua in N = 1, SU(Nc) SUSY theories with Nf > Nc massive fundamental flavors. The consideration of the non-normalizable deformations requires a modified Toric duality. The new approach considers the tachyon condensation between pairs of wrapped D5 branes and anti D5 branes and the resulting ...
متن کاملBreaking in the Metastable Vacua
In the Intriligator-Seiberg-Shih model, we parametrize spontaneous breaking of U(1)R symmetry with two gauge singlets with R-charges 1 and –1. These singlets can play the role of the messengers. The messenger scale is dynamically generated, and hence there is no hierarchy problem between the supersymmetry breaking scale and the messenger scale. In the gauge mediation scenario, supersymmetry bre...
متن کاملMetastable Vacua in Brane Worlds
We analyze vacuum decay in brane world setups, where a free scalar field in five dimensions has a localized potential admitting metastable vacua. We study in particular the bounce solution and its properties in flat and warped spaces. In the latter case, placing into a deeply warped region the term in the potential that lifts the vacuum degeneracy, can increase indefinitely the lifetime of the ...
متن کاملGauge Mediation in Metastable Vacua
Until recently, dynamical supersymmetry breaking seemed an exceptional phenomenon, involving chiral gauge theories with a special structure. Recently it has become clear that requiring only metastable states with broken supersymmetry leads to a far broader class of theories. In this paper, we extend these constructions still further, finding new classes which, unlike earlier theories, do not ha...
متن کاملExplicit R-Symmetry Breaking and Metastable Vacua
We consider O’Raifeartaigh-like models with explicit R-symmetry breaking and analyze the vacuum landscape. Taking such models as candidates for the hidden sector, we analyze the gauge mediation of the supersymmetry breaking, focusing on the effects produced by R-symmetry breaking. First, we construct families of non-R-symmetric models containing only singlet chiral superfields, and determine th...
