Application of AdS/QCD to B physics

TL;DR

This paper applies AdS/QCD models to B meson decays, predicting form factors and observables for semileptonic and dileptonic decay channels, and compares these predictions with experimental data.

Contribution

It introduces a novel application of AdS/QCD to B physics, specifically for calculating transition form factors and decay observables.

Findings

Predicted form factors for B to light meson transitions.

Calculated observables for B→ρℓν and B→K*μ+μ− decays.

Comparison shows reasonable agreement with experimental data.

Abstract

We build on the success of AdS/QCD in predicting diffractive $\rho$ meson production to obtain the transition form factors for B decays to light mesons. Consequently, we predict several observables associated with $B\to \rho\ell\nu$ semileptonic and $B\to K^*\mu^+\mu^-$ dileptonic decays. Our predictions are compared to the available experimental data.
