Abstract

The Exceptional Supersymmetric Standard Model (E 6 SSM) (E6SSM) provides a low energy alternative to the MSSM, with an extra gauged U(1) N U(1)N symmetry, solving the μ‐problem of the MSSM. Inspired by the possible embedding into an E 6 E6 GUT, the matter content fills three generations of E 6 E6 multiplets, thus predicting exciting exotic matter such as diquarks or leptoquarks. We present predictions from a constrained version of the model (cE 6 SSM), (cE6SSM), with a universal scalar mass m 0 , m0, trilinear mass A and gaugino mass M 1/2 . M1/2. We reveal a large volume of the cE 6 SSM 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 cE 6 SSM cE6SSM scenarios, demonstrating that there could be light exotic particles, like leptoquarks and a U(1) N U(1)N Z’ boson, with spectacular signals at the LHC.
