Abstract

We explore $t - b - τ$ Yukawa unification (YU) in a supersymmetric $S U (4)_{c} \times S U (2)_{L} \times S U (2)_{R}$ 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 co-annihilation 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.
