We explore t - b - τ Yukawa unification (YU) in a supersymmetric SU(4) c × SU(2) L × SU(2) R model without imposing a discrete left-right (L-R) symmetry. A number of interesting solutions that are compatible with t - b - τ YU, LSP neutralino dark matter (DM), and LHC and other experimental constraints are identified. In particular, they include gluino-neutralino and stau-neutralino coannihilation scenarios, where the NLSP gluino mass can range from 1–3 TeV. Higgsino-like dark matter solutions are also identified for which gluino masses can approach 5 TeV or so. This scenario will be tested at LHC Run-3 and its future upgrades.
