Electroweak Symmetry Breaking in the E6SSM

TL;DR

This paper explores the E6SSM, an extension of the Standard Model with an extra U(1) symmetry, analyzing its renormalization group evolution, electroweak symmetry breaking, and potential LHC-observable particles.

Contribution

It provides a detailed analysis of electroweak symmetry breaking and particle spectrum predictions in the E6SSM with non-universal Higgs masses at the GUT scale.

Findings

Predicted new exotic particles at the TeV scale.

Identified scenarios with successful electroweak symmetry breaking.

Detailed particle spectrum potentially observable at the LHC.

Abstract

The Exceptional Supersymmetric Standard Model (E6SSM) is an E6 inspired model with an extra gauged U(1) symmetry, which solves the mu-problem in a similar way to the NMSSM but without the accompanying problems of singlet tadpoles or domain walls. It predicts new exotic particles at the TeV scale. We investigate the Renormalisation Group Evolution of the model and test electroweak symmetry breaking for a selection of interesting scenarios with non-universal Higgs masses at the GUT scale. We present a detailed particle spectrum that could be observed at the LHC.
