Yukawa unification with light supersymmetric particles consistent with LHC constraints

Abstract

We investigate supersymmetric models with left-right symmetry based on the group SU(4)c×SU(2)L×SU(2)R (4-2-2) with negative sign of bilinear Higgs potential parameter μ in the context of the latest experimental results. In the backdrop of experimental results from the Large Hadron Collider, we investigate the possibility of Yukawa unification in 4-2-2 and find out the same is still not ruled out. Furthermore, this scenario also provides a satisfactory dark matter candidate. The current experimental bounds on sparticle masses, mass bounds on Higgs particle, updated phenomenological constraints from the rare decays of B meson and the anomalous magnetic moment of muon with the requirement of a Yukawa unified theory having 10% or better third family Yukawa unification are utilized to bound the parametric space of these models.
