SupersymmetricRξgauge and radiative symmetry breaking

Abstract

In this paper we extend the $R_{\xi }$-gauge fixing procedure to supersymmetric theories and calculate the associated superpropagators. We also exhibit a class of supersymmetric field theories which receive nonvanishing loop corrections to their $D$ terms and vacuum expectation values. We show that supersymmetry is not radiatively broken in these theories because of extra symmetries of the superpotential.
