Status of a flavor-maximal nonminimal universal extra dimension model

In this paper we consider an S¹/Z₂ compactified flat extra dimensional scenario where all the standard model states can access the bulk and have generalized brane localized kinetic terms. The flavor structure of brane kinetic terms for the standard model fermions are dictated by stringent flavor bounds on the first two generations implying an U (2 )_QL⊗U (2 )_uR⊗U (2 )_dR flavor symmetry. We consider the constraints on such a scenario arising from dark matter relic density and direct detection measurements, precision electroweak data, Higgs physics, and LHC dilepton searches. We discuss the possibility of such a scenario providing an explanation of the recently measured anomaly in R_K^(*) within the allowed region of the parameter space.
