Measurement of the branching fraction for $B^{0} \to π^{0} π^{0}$ decays reconstructed in 2019-2020 Belle II data

Belle II Collaboration, F. Abudinén, I. Adachi +551

We report the first reconstruction of the $B^{0} \to π^{0} π^{0}$ decay mode at Belle II using samples of 2019 and 2020 data that correspond to 62.8 fb $^{- 1}$ of integrated luminos…

Measurement of the branching fraction of leptonic decay $D_{s}^{+} \to τ^{+} ν_{τ}$ via $τ^{+} \to π^{+} π^{0} ν ˉ_{τ}$

M. Ablikim, M. N. Achasov, P. Adlarson +503

By analyzing $6.32 fb^{- 1}$ of $e^{+} e^{-}$ annihilation data collected at the center-of-mass energies between 4.178 and 4.226\,GeV with the BESIII detector, we determine the…
