The Exceptional Supersymmetric Standard Model (E 6 SSM) \n(E6SSM) \n provides a low energy alternative to the MSSM, with an extra gauged U(1) N \nU(1)N \n symmetry, solving the μ‐problem of the MSSM. Inspired by the possible embedding into an E 6 \nE6 \n GUT, the matter content fills three generations of E 6 \nE6 \n multiplets, thus predicting exciting exotic matter such as diquarks or leptoquarks. We present predictions from a constrained version of the model (cE 6 SSM), \n(cE6SSM), \n with a universal scalar mass m 0 , \nm0, \n trilinear mass A and gaugino mass M 1/2 . \nM1/2. \n We reveal a large volume of the cE 6 SSM \ncE6SSM \n 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 \ncE6SSM \n scenarios, demonstrating that there could be light exotic particles, like leptoquarks and a U(1) N \nU(1)N \n Z’ boson, with spectacular signals at the LHC.
