Dark matter, sparticle spectroscopy and muon ( g − 2) in SU(4) c × SU(2) L × SU(2) R

bstract We explore the sparticle mass spectra including LSP dark matter within the framework of supersymmetric SU(4) c × SU(2) L × SU(2) R (422) models, taking into account the constraints from extensive LHC and cold dark matter searches. The soft supersymmetry-breaking parameters at M GUT can be non-universal, but consistent with the 422 symmetry. We identify a variety of coannihilation scenarios compatible with LSP dark matter, and study the implications for future supersymmetry searches and the ongoing muon g-2 experiment.
