Testing Spontaneous Parity Violation at the LHC
Chin-Aik Lee, Qaisar Shafi
TL;DR
This paper proposes a supersymmetric left-right symmetric model with a discrete C-parity, predicting new particles at the TeV scale that could be detected at the LHC, offering insights into parity violation.
Contribution
It introduces a novel supersymmetric left-right model with a natural missing partner mechanism and predicts accessible new particles at the TeV scale for LHC experiments.
Findings
A supersymmetric SU(2)_L x SU(2)_R x U(1)_B-L model with strict left-right symmetry.
A natural missing partner mechanism ensures only one Higgs doublet pair survives.
Potentially light new particles accessible at the LHC in the TeV range.
Abstract
We construct a supersymmetric SU(2)_L X SU(2)_R X 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 W_R^+- will be accessible at the LHC.
