The B -> pi l nu form factor from unquenched lattice QCD with
domain-wall light quarks and relativistic b-quarks    [PDF]

Taichi Kawanai, Ruth S. Van de Water, Oliver Witzel

We report on a lattice-QCD calculation of the B to pi l nu form factor with domain-wall light quarks and relativistic b-quarks using the 2 + 1 flavor domain-wall fermion and Iwasaki gauge-field ensembles generated by the RBC and UKQCD Collaborations. We present initial results obtained from the coarser (a ~ 0.11 fm) 24^3 lattices and some of the finer (a ~ 0.086 fm) 32^3 lattices.
