Abstract

Vub is the smallest and least known of all CKM matrix elements; it is currently determined primarily through the exclusive process B → πℓν̄, and additional channels to determine it are welcomed by the community. We will present progress toward a lattice QCD determination of |Vub| from the B → ππℓν̄ process, where the ππ system is in a P-wave and features the p(770) resonance as an enhancement. After an overview of the theoretical framework, we will discuss some preliminary results.
