NP models with extended gauge groups and extra dimensions: Impact on flavour observables in RS$_c$

TL;DR

This paper investigates how the Randall-Sundrum model with custodial protection (RS_c) affects flavor observables, especially rare B decays, by analyzing deviations from Standard Model predictions in FCNC processes.

Contribution

It provides a detailed analysis of flavor observables within the RS_c model, offering predictions for rare B decays and explaining recent deviations in angular distributions.

Findings

RS_c model can account for deviations in $B^0 o K^{*0} \mu^+ \mu^-$ angular distributions.

Predictions for other rare B decays are provided within the RS_c framework.

The model suggests new contributions to Wilson coefficients that could explain experimental tensions.

Abstract

Deviations with respect to Standard Model predictions have recently shown up in angular distributions of the FCNC induced mode $B^0 \to K^{*0} \mu^+ \mu^-$. Within New Physics models, such tensions might be explained by new contributions to the Wilson coefficients of the effective Hamiltonian governing this decay. I discuss the issue in the framework of the Randall-Sundrum model with custodial protection (RS$_c$), giving also predictions for other rare $B$ decays.
