Quartet decoupling and supersymmetric dynamical gauge symmetry breaking

Abstract

The supersymmetric extension of the conventional mechanism of dynamical gauge symmetry breaking is presented in the special case where all Goldstone bosons are doubled. The models considered are strongly interacting supersymmetric gauge theories exhibiting a chiral symmetry breaking pattern G → H where G/H is a symmetric space. A subgroup G w of G is weakly gauged, and the resulting mass generation mechanisms for the Bose and Fermi gauge fields of G w are studied. Particular emphasis is given to the decoupling of unphysical degrees of freedom from the spectrum through the quartet decoupling mechanism.
