TL;DR

This paper studies the skewed parton distributions for B to pi transitions, combining theoretical models and phenomenological parameters to predict form factors and decay branching ratios in B meson decays.

Contribution

It introduces a detailed analysis of b-u skewed parton distributions for B->pi transitions and provides predictions for form factors and decay rates using a phenomenological approach.

Findings

Predicted B->pi transition form factors.

Estimated branching ratios for semi-leptonic B decays.

Analyzed contributions from wave functions, annihilations, and resonances.

Abstract

We investigate the b-u skewed parton distributions (SPDs) for B->pi transitions and determine the contributions from several sources (overlaps of soft light-cone wave functions, quark-antiquark annihilations and meson resonances). The B->pi transition form factors, which are relevant in exclusive semi-leptonic and non-leptonic B-decays, are obtained by integrating the b-u SPDs over the momentum fraction x. A phenomenological determination of the relevant parameters allows us to predict the form factors and to obtain the branching ratios for semi-leptonic B->pi decays.
