The search for new physics signals in observables of rare dileptonic Bs Meson Decays using AdS/QCD correspondence and QCD SR models

Abstract

The main goal of this theoretical research project aimed to predict decay observables for the rare dileptonic process Bs --> φµ+µ-. Specifically, the differential branching ratio was computed using both QCDSR and AdS/QCD methods. Emphasis was placed on the latter method in order to probe and investigate the model dependence of the theoretical predictions of rare B decays, which are essential in search of New Physics beyond the Standard Model. Our preliminary results indicate that the discrepancies between the experimental results and the AdS/QCD correspondence model predictions are lower than those from the QCD Sum Rules, which are often referred to as the SM predictions. The effects of higher twist distribution amplitudes on the differential branching ratio B --> K*νν of were also investigated.
