Low energy consequences from supersymmetric models with left-right symmetry

TL;DR

This paper explores the low energy implications of supersymmetric models with left-right symmetry, addressing gauge hierarchy, parameter constraints, and potential experimental signals in rare decays.

Contribution

It analyzes how specific supersymmetric models with extended gauge groups resolve hierarchy and $$ problems and predicts testable low-energy phenomena.

Findings

Constraints on MSSM parameters like $ an eta$, $B$, and $$ are identified.

Predictions for sparticle and Higgs spectra are provided.

Enhanced sensitivity could make rare decay processes observable.

Abstract

We consider several low energy consequences arising from a class of supersymmetric models based on the gauge groups $SU(2)_L\times SU(2)_R \times U(1)_{B-L}$ and $SU(4)_C\times SU(2)_L \times SU(2)_R$ in which the gauge hierarchy and $\mu$ problems have been resolved. There are important constraints on the MSSM parameters $\tan \beta (\simeq m_t/m_b)$, $B$ and $\mu$, and we discuss how they are reconciled with radiative electroweak breaking. We also consider the ensuing sparticle and Higgs spectroscopy, as well as the decays $b\to s \gamma$ and $\mu \to e \gamma$. The latter process may be amenable to experimental tests through an order of magnitude increase in sensitivity.
