Measurement of the (bar B)0 → D*+(ell)-(bar ν) Branching Fraction with a Partial Reconstruction Technique
Description
Presented is a precise measurement of the (bar B)0 → D*+(ell)-(bar ν)#ell# branching fraction using 81.47 fb-1 of data collected with the BABAR detector at the PEP-II e+e- storage ring at the Stanford Linear Accelerator Center. The measurement was performed by partially reconstructing the D*+ meson from (bar B)0 → D*+(ell)-(bar ν)#ell# decays using only the soft pion of the D*+ → D0π+ decay to reconstruct its four vector. The branching fraction was measured to be Β((bar B)0 → D*+(ell)-(bar ν)#ell#) = (4.91 ± 0.01stat ± 0.15syst)%.
