Description
One of the most persistent tensions in flavor physics is the $V_{cb}$ puzzle, a long standing tension between inclusive and exclusive determinations of the CKM matrix element $V_{cb}$. After lattice QCD has been applied extremely successfully in the calculation of physical quantities needed for the exclusive determination of $V_{cb}$ for many years, now also methods for computing inclusive observables on the lattice are available.
First results obtained using these methods at an unphysical $m_b$ are presented, systematically compared to the predictions the operator product expansion and future prospects are discussed.
