Abstract
AbstractWe study the minimal supersymmetric standard model (MSSM) with minimal flavor violation (MFV), imposing constraints from flavor physics observables and MSSM Higgs searches, in light of the recent discovery of a 125 GeV Higgs boson by ATLAS and CMS. We analyze the electroweak vacuum stability conditions to further restrict the MSSM parameter space. In addition, a connection to ultraviolet physics is shown via an implementation of renormalization group running, which determines the TeV-scale spectrum from a small set of minimal supergravity parameters. Finally, we investigate the impact from dark matter direct detection searches. Our work highlights the complementarity of collider, flavor and dark matter probes in exploring the MSSM, and shows that even in a MFV framework, flavor observables constrain the MSSM parameter space well beyond the current reach of direct SUSY particle searches.
Highlights
Mixing unavoidably leads to irreducible contributions to low energy flavor observables, in particular in the Flavor Changing Neutral Current (FCNC) decays Bs → μ+μ− and B → Xsγ, even if all soft masses are flavor blind

In the MSSM with large tan β, direct searches of the heavy Higgs bosons become especially sensitive and, the exchange of heavy Higgs bosons can lead to large dark matter direct detection cross sections, giving additional complementary means to probe this region of parameter space
Summary
We briefly review the MSSM with MFV. Throughout this work, in addition to MFV, we assume minimal CP violation, i.e. the phase of the CKM matrix is the only source of CP violation, while all the MSSM parameters are CP conserving.
