- The Higgs, Flavor and Large At in Extended GMSB
- Time: 3:00 pm - 4:00 pm
- Place: 5280 Chamberlin Hall
- Speaker: Jared Evans
- Abstract: The observed Higgs at 126 GeV requires large tuning in the MSSM. This tuning is particularly bad in gauge mediated SUSY breaking (GMSB), as the large A-terms that can ameliorate this tuning are absent at the messenger scale. Extending GMSB through the addition of superpotential couplings between the MSSM and messenger superfields can generate these A-terms to reduce the severity of the tuning problems in GMSB. There are a variety of couplings that one can consider, but those best for tuning provide a source of flavor violation beyond the standard model Yukawas. However, there are several features of the extended GMSB models that allow them to relax the SUSY flavor problem. I will review extended GMSB, discuss these flavor issues in detail, and also discuss some of the phenomenological prospects for discovering these models.
