Posterior samples of BGL coefficients for $B \to D^\ast \ell\bar\nu_\ell$ form factors

Abstract

This dataset contains posterior samples of BGL coefficients which parameterise the $B \to D^\ast$ hadronic form factors, generated as part of the analysis for the paper " Angular Analysis of $B \to D^\ast \ell\bar\nu_\ell$ from Lattice and Experiment: $|V_{cb}|$ and New Physics Constraints", arXiv:2606.23410. The script fetches the posterior samples, calculates the bootstrap central values and errors quoted in the aforementioned paper, and constructs the corresponding form-factor predictions at some example $q^2$ points. To run from the root directory: python3 BtoDstar_results.py
