Yukawa Unification Predictions with effective "Mirage" Mediation

TL;DR

This paper investigates the implications of gauge and third family Yukawa coupling unification within an effective 'mirage' mediation framework, analyzing its compatibility with LHC data and low-energy observables.

Contribution

It introduces a novel effective 'mirage' mediation boundary condition set for Yukawa unification and performs a comprehensive fit to experimental data within the MSSM.

Findings

Good fit to low-energy observables achieved.

SUSY spectrum significantly different from previous models.

Supports Yukawa unification with specific boundary conditions.

Abstract

In this letter we analyze the consequences, for the LHC, of gauge and third family Yukawa coupling unification with a particular set of boundary conditions defined at the GUT scale, which we characterize as effective "mirage" mediation. We perform a global chi-squared analysis including the observables M_W, M_Z, G_F, alpha_em, alpha_s(M_Z), M_top, m_b(m_b), M_tau, BR(B -> X_s gamma), BR(B_s -> mu^+ mu^-) and M_{h}. The fit is performed in the MSSM in terms of 10 GUT scale parameters, while tanb and mu are fixed at the weak scale. We find good fits to the low energy data and a SUSY spectrum which is dramatically different than previously studied in the context of Yukawa unification.
