Color and charge breaking minima in the MSSM

Abstract

The scalar potential of theories with broken supersymmetry can have a number of local minima characterized by different gauge groups. Symmetry properties of the physical vacuum constrain the parameters of the MSSM. We discuss these constraints, in particular those that result from the vacuum stability with respect to quantum tunneling.Comment: 3 pages, latex, macros and three figures included, complete postscript file is available at ftp://dept.physics.upenn.edu/pub/Kusenko/SUSY96.ps .
