Description

In the quest for a precise determination of the smallest CKM matrix element, $| V_{u b} |$ , the decay $B \to ρ ℓ \bar{ν}$ offers a promising route to resolving the discrepancy between exclusive and inclusive determinations. This talk will outline our progress on a lattice QCD calculation of the $B \to ρ ℓ \bar{ν}$ form factors, where the $ρ$ resonance is treated as an enhancement in P-wave $π π$ scattering. After discussing the main computational hurdles, I will present details of our calculation and results obtained on a gauge ensemble with 2+1 dynamical quarks at a pion mass of approximately 320 MeV.
