Abstract

We discuss two striking Large Hadron Collider (LHC) signatures of the constrained version of the exceptional supersymmetric standard model, based on a universal high-energy soft scalar mass m0, soft trilinear coupling A0 and soft gaugino mass M1/2. The first signature we discuss is that of light exotic color triplet charge 1/3 fermions, which we refer to as D-fermions. We calculate the LHC production cross section of D-fermions, and discuss their decay patterns. Secondly we discuss the E 6 type U(1)N spin-1 Z gauge boson and show how it may decay into exotic states, increasing its width and modifying the line shape of the dilepton final state. We illustrate these features using two representative exceptional supersymmetric standard model benchmark points, including an "early LHC discovery" point, giving the Feynman rules and numerical values for the relevant couplings in order to facilitate further studies.
