## Radiative breaking of the minimal supersymmetric left–right model

## 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 also 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. We obtained mass limits on the SU(2) _{R}×U(1) _{BL} sector by direct search results at the LHC as well as lepton-gaugino mixing bounds from the LEP precision data.
