Abstract

Grand unified theories open the possibility to transfer the neutrino mixing matrix U_PMNS to the quark sector. This is accomplished in a controlled way in a supersymmetric grand-unified model proposed by Chang, Masiero and Murayama (CMM model) where the atmospheric neutrino mixing angle induces large new b -> s and tau -> mu transitions. Relating the supersymmetric low-energy parameters to seven new parameters a₀, m₀², m_tildeg, D, xi, tan beta and arg(mu) of this SO(10) model, we perform a correlated study of several flavour-changing neutral current (FCNC) processes. The CMM model can serve as an alternative benchmark scenario to the popular constraint MSSM.
