Title: Measurement of the branching fraction of B D ( * ) π ν at Belle using hadronic tagging in fully reconstructed events

Abstract

We report a measurement of the branching fractions of the decays B→D(*)πℓv. The analysis uses 772×10 6 $$B\overline{B}$$ pairs produced in e +e -→Y(4S) data recorded by the Belle experiment at the KEKB asymmetric-energy e +e - collider. The tagging B meson in the decay is fully reconstructed in a hadronic decay mode. On the signal side, we reconstruct the decay B→D(*)πℓv(l=e,μ). The measured branching fractions are B(B +→D -π ++v) = [4.55±0.27 (stat.)±0.39 (syst.)]×10 -3, B(B 0→$$\overline{D}$$ 0π -+ν)=[4.05±0.36 (stat.)±0.41 (syst.)]×10 -3, B(B +→D*-π ++ν)=[6.03±0.43 (stat.)±0.38 (syst.)]×10 -3, and B(B 0→$$\overline{D}$$* 0π -+ν)=[6.46±0.53 (stat.)±0.52 (syst.)]×10 -3. These are in good agreement with the current world-average values.
