We present a lattice QCD calculation of B → πlν semileptonic decay form factors in the small pion recoil momentum region. The calculation is performed on a quenched 16 3 × 48 lattice at β = 5.9 with the NRQCD action including the full 1/M terms. The form factors f 1 (v · k π) and f 2 (v · k π) defined in the heavy quark effective theory for which the heavy(More)
