Description

The desire for additional determinations of the CKM matrix element Vub and a long-standing 2-3σ discrepancy between results from inclusive BXu and exclusive Bπ processes motivate the study of Bπ semileptonic form factors on the lattice. The status of our preliminary Bπν results will be discussed by highlighting updates to our analysis. The analysis is carried out on a subset of the RBC/UKQCD 2+1f Iwasaki gauge action ensembles, with b quarks simulated using the Columbia formulation of the relativistic heavy quark action, and the light valence-quarks simulated with domain wall fermions. The final results of this project will provide updates to the 2015 RBC/UKQCD Bπν result.
