Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, K. Adamczyk, H. Ahmed, Y. Ahn | Summary: We present a measurement of the branching fraction of $B^+totau^+nu_tau$ decays using $(387pm6)times 10^6$ $Upsilon(4S)$ collected between 2019 and 2022 with the Belle II detector at the SuperKEKB $e^+e^-$ collider. We reconstruct the accompanying […]
