near the endpoint of the electron momentum spectrum from semileptonic B-meson decays Belle Collaboration

We report measurements of partial branching fractions of inclusive charmless semileptonic B-meson decays at the endpoint of the electron momentum spectrum. The measurements are made in six overlapping momentum intervals that have lower bounds ranging from 1.9 GeV/c to 2.4 GeV/c and a common upper bound of 2.6 GeV/c, as measured in the centre of mass frame. The results are based on a sample of 29 million BB pairs, accumulated by the Belle detector at the KEKB asymmetric e+e− collider operating on the Υ(4S) resonance. In the momentum
