Description
In this article, we investigate the potential of the angular distribution of the $B \to D^* \ell \nu_\ell$ process to search for new physics signals. The Belle collaboration has analysed it to constraint $V_{cb}$ and the $B\to D^*$ form factors, under the assumption of the Standard Model. With the newly released lattice QCD data, we can perform a simultaneous fit of the form factors, $V_{cb}$ as well as new physics parameters. We use the Belle data and the lattice data to constrain right-handed new physics. In addition, we also generate unbinned pseudo-dataset and perform a sensitivity study on {more general new physics} models, using the lattice data.
