Radiative breaking of the minimal supersymmetric left-right model

We study a variation to the SUSY Left-Right symmetric model based on the gauge group SU(3)(c) x SU(2)(L) x SU(2)(R) x 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) x U(1)(BL) -> U(1)(Upsilon) 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) x 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. (C) 2016 The Authors.
