| dc.description.abstract | The first measurements of differential branching fractions of inclusive semileptonic B → Xulþνl decays are performed using the full Belle data set of 711 fb−1 of integrated luminosity at the ϒð4SÞ resonance and for l ¼ e, μ. With the availability of these measurements, new avenues for future shape-function modelindependent determinations of the Cabibbo-Kobayashi-Maskawa matrix element jVubj can be pursued to gain new insights in the existing tension with respect to exclusive determinations. The differential branching fractions are reported as a function of the lepton energy, the four-momentum-transfer squared, light-cone momenta, the hadronic mass, and the hadronic mass squared. They are obtained by subtracting the backgrounds from semileptonic B → Xclþνl decays and other processes, and corrected for resolution and acceptance effects | en_US |
