We explore the sparticle and Higgs spectroscopy of an SU(5) inspired extension of the constrained minimal supersymmetric standard model. The universal soft parameter m₀ is replaced by m₅̅ and m₁₀, where m₅̅ and m₁₀ denote universal soft scalar masses associated with fields in the five- and ten-dimensional representations of SU(5). The special case m₅̅ ≪ 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.
