Yukawa unification in SUSY SO(10) for mu<0 consistent with muon g-2 and b->s gamma

TL;DR

This paper demonstrates that Yukawa unification in SUSY SO(10) models with mu<0 can align with muon g-2 and b->s gamma measurements, predicting specific ranges for gluino masses and sparticle spectra.

Contribution

It shows the compatibility of mu<0 Yukawa unification with experimental constraints using non-universal gaugino masses from an SO(10) F-term, providing concrete sparticle mass predictions.

Findings

Gluino mass predicted between 500-700 GeV or 900 GeV-1.6 TeV.

Compatibility of mu<0 Yukawa unification with muon g-2 and b->s gamma within 2σ.

Specific sparticle spectrum predictions consistent with relic neutralino abundance.

Abstract

It is shown that top-bottom-tau Yukawa unification for \mu<0 can be consistent with (g-2)_\mu and b->s \gamma. This happens for non-universal gaugino masses which are assumed to be generated by the F-term vev in a 54-dimensional representation of SO(10). The requirement of (g-2)_\mu and b->s \gamma being within 2\sigma from the experimental central values, together with the correct relic abundance of neutralinos, leads to rather definite predictions for sparticle spectrum. In particular, the gluino mass is predicted to be between 500 and 700 GeV or between 900 GeV and 1.6 TeV.
