Measurement of the Ratio of Partial Branching Fractions of Inclusive to and the Ratio of their Spectra with Hadronic Tagging
Belle Collaboration, M. Hohmann, P. Urquijo +157
We present a measurement of the ratio of partial branching fractions of the semi-leptonic inclusive decays, to $\overline{B} \to X_{c} \ell…
