Abstract: We explore the sparticle and Higgs spectroscopy of an SU5 inspiredextension of the constrained minimal supersymmetric standard model CMSSM. Theuniversal soft parameter m 0 is replaced by m {\bar 5} and m {10}, wherem {\bar 5} and m {10} denote universal soft scalar masses associated withfields in the five and ten dimensional representations of SU5. The specialcase m {\bar 5} << m {10} yields a rather characteristic sparticle spectroscopywhich can be tested at the LHC. We highlight a few benchmark points in whichthe lightest neutralino saturates the WMAP bound on cold dark matter abundance.
