Soft Probes of SU(5) Unification

We explore the sparticle and Higgs spectroscopy of an SU(5) inspired extension of the constrained minimal supersymmetric standard model (CMSSM). The universal soft parameter m0 is replaced by m5̄ and m10, where m5̄ and m10 denote universal soft scalar masses associated with fields in the five and ten dimensional representations of SU(5). The special case m5̄ ≪ m10 yields a rather characteristic sparticle spectroscopy which can be tested at the LHC. We highlight a few benchmark points in which the lightest neutralino saturates the WMAP bound on cold dark matter abundance.
