B_s-B_s-bar mixing in an SO(10) SUSY GUT model

Abstract

We perform a renormalisation group analysis of the SO(10) model proposed by Chang, Masiero and Murayama, which links the large atmospheric neutrino mixing angle to loop-induced transitions between right-handed b and s quarks. We compute the impact on B_s-B_s-bar mixing and find that the mass difference in the B_s system can exceed its Standard Model value by a factor of 16.
