More on Conformally Sequestered SUSY Breaking
We extend our models for conformal sequestering of dynamical supersymmetry breaking with decoupling vector-like matter in several different ways. These extensions enable us to simplify concrete model building, in particular, rendering large gauge group and ad hoc global symmetry for sequestering unnecessary. Conformal sequestering appears highly natural in such circumstances.
متن کاملHypercharged Conformally Sequestered Gauge Mediation
The Bμ/μ solution in GMSB via the hidden sector dynamics is simple and natural. However, it has some obstacles to be physical. To circumvent this situation, we introduce the visible and the hidden branes, each of which has its own U(1) symmetry, in a five dimensional setup. In the bulk we allow Chern-Simons coupling between the visible and the hidden U(1)s which gives an enhancement of the mass...

متن کاملGauge Mediation with Sequestered Supersymmetry Breaking
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 in the supersymmetry breaking sector offers attractive solutions to both problems. The correct mass scale of the μ and Bμ terms is generated by taking the gravitino mass of O(100)GeV without causing the flavor-changi...
متن کاملMore on Supersymmetric Tensionless Rotating
Rotating IIB strings in AdS5 × S become ultra-relativistic, and hence effectively tensionless, in the limit of large angular momentum on S. We have shown previously that such tensionless strings may preserve supersymmetry. Here we extend this result to include a class of supersymmetric tensionless strings with arbitrary SO(6) angular momentum. We close with some general comments on tensionless ...
