Flavor and Lepton Universality Violation Phenomena in F-Theory Inspired GUTs

Abstract

We discuss low energy implications of F-theory GUTs based on SU(5) extended by a U(1)' symmetry which couples non-universally to the three chiral families. Several classes of anomaly free models are obtained, distinguished with respect to the U(1)' charges of the representations, and possible extra zero modes coming in vector-like pairs. We considered the case where the spontaneous breaking of the U(1)' symmetry occurs at a few TeV scale and we compute the observables of several flavor violation exotic processes in the effective theory. Particular cases interpreting the B-meson anomalies observed in LHCb experiments are also discussed.
