Yukawa Unification with light supersymmetric particles consistent with LHC constraints

Abstract

We investigate supersymmetric models with left-right symmetry based on the group $SU(4{)}_c\times SU(2{)}_L\times SU(2{)}_R$ ($4$-$2$-$2$) with negative sign of bilinear Higgs potential parameter $\mu$ 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.
