Description
$𝑉_{𝑢𝑏}$ is the smallest and least known of all CKM matrix elements; it's currently determined primarily through the exclusive process $B \to \pi \ell \bar{\nu}$, and additional channels to determine it are welcomed by the community. I will present progress toward a lattice QCD determination of the $𝑉_{𝑢𝑏}$ matrix from the $B \to \pi \pi \ell \bar{\nu}$ process, where the $\pi\pi$ system is in a P-wave and features the $\rho(770)$ resonance as an enhancement. After an overview of the theoretical framework, I will discuss some preliminary results.
