Charge and Color Breaking minima in the MSSM: the bottom-up connection

Abstract content

The Minimal Supersymmetric Standard Model (MSSM) is known for the possibility of creating (unwanted) charge and color breaking minima. Well-known bounds on MSSM parameters are known for special scenarios with an alignment of vacuum expectation values (vevs) in the direction of up-type or dow-type fields only. From the one-loop stability condition in the up-type Higgs direction, we find a new constraint from the stability against sbottom vevs aligned with the up-Higgs. By this constraint, we exclude regions with large tanbeta and large mu-parameters.
