Abstract

We study a variation to the SUSY Left–Right symmetric model based on the gauge group (SU(3){c}×SU(2){L}×SU(2){R}×U(1){BL}). Beyond the quark and lepton superfields we only introduce a second Higgs bidoublet to produce realistic fermion mass matrices. This model does not include any (SU(2){R}) triplets. We calculate renormalization group evolutions of soft SUSY parameters at the one-loop level down to low energy. We find that an (SU(2){R}) slepton doublet acquires a negative mass squared at low energies, so that the breaking of (SU(2){R}×U(1){BL}→U(1){Y}) is realized by a non-zero vacuum expectation value of a right-handed sneutrino. Small neutrino masses are produced through neutrino mixings with gauginos. Mass limits on the (SU(2){R}×U(1)_{BL}) sector are obtained by direct search results at the LHC as well as lepton-gaugino mixing bounds from the LEP precision data.
