Abstract

The measurement of an inclusive partial branching fraction for charmless semileptonic B decay and the extraction of |Vub| was discussed. The candidates for B → Xulv were identified with a Xu reconstruction method based on neutrino reconstruction.It was found that the result of |Vub| = (4.66 ± 0.760 × 10-3 was consistent with the previous inclusive measurements. Analysis shows that the error from the cluster finding efficiency was estimated by reducing the photon-finding efficiency within its uncertainity.
