Measurement of the branching fraction of $B^{+}\to {\tau }^{+}{\nu }_{\tau }$ decays with the semileptonic tagging method and the full Belle data sample

Belle Collaboration, A. Abdesselam, I. Adachi +392

We report a measurement of the branching fraction of $B^{+}\to {\tau }^{+}{\nu }_{\tau }$ decays using a data sample of $772\times 10^{6}B\bar{B}$ pairs, collected at the ${\rm Y}(4S)$ resonance with the…
