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

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.
