RS-A4 relaxation of flavor and CP violation

摘要

I discuss a model based on an A4 bulk flavor symmetry in the Randall-Sundrum (RS) setup. After discussing the setup and leading order results for the masses and mixings of quarks and leptons, I elaborate on the effect of higher order “cross-talk” corrections, their contributions to flavor violating processes and the resulting constraints on the model parameter space and the Kaluza-Klein (KK) mass scale. In addition, I present a systematic study of higher order corrections to the PMNS matrix in light of the recent measurements of θ 13 > 0 by RENO and Daya Bay. Finally, I also comment on the model new physics contributions to (B_{s,d}tomu^{+}mu^-) and μ → eγ, in light of the new upper bounds recently set by the LHCb and MEG experiment.
