Phenomenological consequences of the constrained exceptional supersymmetric standard model

We reveal a large volume of the cE6SSM parameter space where the correct breakdown of the gauge symmetry is achieved and all experimental constraints satisfied. We predict a hierarchical particle spectrum with heavy scalars and light gauginos, while the new exotic matter can be light or heavy depending on parameters. We present representative cE6SSM scenarios, demonstrating that there could be light exotic particles, like leptoquarks and a U(1)N Z’ boson, with spectacular signals at the LHC.

Abstract

The Exceptional Supersymmetric Standard Model (E6SSM) provides a low energy alternative to the MSSM, with an extra gauged U(1)N symmetry, solving the ??problem of the MSSM. Inspired by the possible embedding into an E6 GUT, the matter content fills three generations of E6 multiplets, thus predicting exciting exotic matter such as diquarks or leptoquarks. We present predictions from a constrained version of the model (cE6SSM), with a universal scalar mass m0, trilinear mass A and gaugino mass M1/2. We reveal a large volume of the cE6SSM parameter space where the correct breakdown of the gauge symmetry is achieved and all experimental constraints satisfied. We predict a hierarchical particle spectrum with heavy scalars and light gauginos, while the new exotic matter can be light or heavy depending on parameters. We present representative cE6SSM scenarios, demonstrating that there could be light exotic particles, like leptoquarks and a U(1)N Z’ boson, with spectacular signals at the LHC.
