RD(*) in custodial warped space Carena, Marcela Megías Fernández, Eugenio Quirós, Mariano Wagner, Carlos Phenomenology of Field Theories in Higher Dimensions Phenomenology of Large extra dimensions Flavor physics experiments allow to probe the accuracy of the Standard Model (SM) description at low energies, and are sensitive to new heavy gauge bosons that couple to quarks and leptons in a relevant way. The apparent anomaly in the ratios of the decay of B-mesons into D-mesons and different lepton flavors, RD(*) = B(B → D(*)τν)=B(B → D(*)lν) is particularly intriguing, since these decay processes occur at tree-level in the SM. Recently, it has been suggested that this anomaly may be explained by new gauge bosons coupled to right-handed currents of quarks and leptons, involving light right-handed neutrinos. In this work we present a well-motivated ultraviolet complete realization of this idea, embedding the SM in a warped space with an SU(2)L⊗SU(2)R⊗U(1)B-L bulk gauge symmetry. Besides providing a solution to the hierarchy problem, we show that this model, which has an explicit custodial symmetry, can explain the RD(*) anomaly and at the same time allow for a solution to the RK(*) anomalies, related to the decay of B-mesons into K-mesons and leptons, RK(*) = B(B → K(*)µµ)=B(B → K(*)ee). In addition, a model prediction is an anomalous value of the forward-backward asymmetry AbFB, driven by the ZbRbR coupling, in agreement with LEP data. 2024-10-10T07:36:21Z 2024-10-10T07:36:21Z 2018-12-07 journal article Carena, M., Megías, E., Quirós, M. et al.
