Abstract: We construct a supersymmetric model in which a discrete symmetry (C-parity) implements strict left–right symmetry in the scalar (Higgs) sector. Although two electroweak bidoublets are introduced to accommodate the observed fermion masses and mixings, a natural missing partner mechanism insures that a single pair of MSSM Higgs doublets survives below the left–right symmetry breaking scale. If this scale happens to lie in the TeV range, several new particles potentially much lighter than the charged gauge bosons will be accessible at the LHC. [Copyright &y& Elsevier]

Abstract: We construct supersymmetric models with spontaneously broken left–right symmetry (C-parity). The minimal supersymmetric standard model (MSSM) can be recovered at low scales by exploiting the missing partner mechanism. The field content is compatible with realistic fermion masses and mixings, proton lifetime is close to or exceeds the current experimental bounds, and supersymmetric hybrid inflation can be implemented to take care of C-parity domain walls as well as magnetic monopoles, and to realize the observed baryon asymmetry via non-thermal leptogenesis.
