Holographic light-front QCD in B meson phenomenology

TL;DR

This paper applies holographic light-front QCD to derive meson wavefunctions, enabling predictions of transition form factors for B meson decays, and compares these results with lattice QCD, sum rules, and experimental data.

Contribution

It introduces a novel use of holographic light-front QCD to calculate meson distribution amplitudes and B decay form factors, providing a new approach in phenomenological studies.

Findings

Predicted transition form factors agree with lattice QCD and sum rule results.

Provided decay form factor predictions consistent with experimental data.

Demonstrated the effectiveness of holographic light-front QCD in B meson phenomenology.

Abstract

The light-front wavefunction for mesons predicted by holographic light-front QCD is used to obtain the light-cone distribution amplitudes for the light vector mesons and the transition form factors for B and $B_s$ decays to $\rho$, $K^*$ and $\phi$ mesons. Here, I present some of our predictions as compared to lattice QCD, OCD sum rules and the available experimental data.
