Potential and limitations of machine-learning approaches to inclusive $|V_{ub}|$ determinations

Anke Biekötter, Ka Wang Kwok, Benjamin D. Pecjak

The determination of $|V_{ub}|$ in inclusive semileptonic $B\to X_u\ell \nu$ decays will be among the pivotal tasks of Belle II. In this paper we study the potential and limitation…
