    • Abstract


      It is shown that SU(2)×U(1) can be broken at the tree level, without the occurrence of global potential minima that break U(1)e.m., in supergravity models that are more general than those proposed by Nilles, Srednicki and Wyler. The study comprises an analysis of models with a general soft supersymmetry-breaking structure as well as those of the Hall-Lykken-Weinberg type.
