The author studied supergravity induced radiative breaking of SU/sub R/(2)XU(1) group in left-right symmetric theories of electroweak interactions. He found that in order to have a minimum that breaks SU/sub R/XU(1) symmetry leaving SU/sub L/(2) intact, the parity has to be broken at a scale much above the TeV region. The author shows that if a parity odd singlet is introduced in the theory that picks up VEV at superheavy scale then SU/sub R/(2)XU(1) group breaks down radiatively via a nonzero VEV acquired by right handed s-neutrino. He analyses the resulting mass spectrum of charged and neutral fermions and finds that theory does allow two low mass fermionic states that are predominantly tau lepton and the corresponding neutrino. Then calculating the K/sub L/-K/sub S/ mass difference he finds that supersymmetric contributions negate a well known constraint on right handed mass scale (M/sub W/sub R// > 1.6 TeV). This implies that left-right theories could be a nontrivial alternative to standard model at low energies. Finally, a method of deriving renormalization group equations (RGE) in explicitly broken supersymmetric theories using fully superspace methods is prescribed.
