The constrained E6SSM

TL;DR

This paper analyzes the predictions of a constrained exceptional supersymmetric standard model, highlighting its distinctive light sparticle spectrum and potential early signals at the LHC due to exotic particles and a Z' boson.

Contribution

It introduces a constrained version of the E6SSM with specific universal soft parameters and explores its phenomenological implications, including exotic particles and collider signatures.

Findings

Light gluino, wino-like neutralino, and bino-like neutralino are predicted.

Heavier sparticles except the lighter stop are significantly heavier.

Potential early signals at the LHC from exotic fermions, scalars, and a Z' boson.

Abstract

We discuss the predictions of a constrained version of the exceptional supersymmetric standard model (cE6SSM), with a universal high energy soft scalar mass, soft trilinear coupling and soft gaugino mass. The spectrum includes a light gluino, a light wino-like neutralino and chargino pair and a light bino-like neutralino, with other sparticle masses except the lighter stop being much heavier. We also discuss scenarios with an extra light exotic colour triplet of fermions and scalars and a TeV scale Z', which lead to early exotic physics signals at the LHC.
