Testing spontaneous parity violation at the LHC

We construct a supersymmetric SU(2)L×SU(2)R×U(1)B−L 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 SU(2)R charged gauge bosons WR± will be accessible at the LHC.
