Search for the decay $B^{0} \to K^{* 0} τ^{+} τ^{-}$ at the Belle experiment

Belle Collaboration, T. V. Dong, T. Luo +193

This letter presents a search for the rare flavor-changing neutral current process $B^{0} \to K^{* 0} τ^{+} τ^{-}$ using data taken with the Belle detector at the KEKB asym…

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 time-integrated mixing probability $χ_{d}$ with a semileptonic double-tagging strategy and $34.6 fb^{- 1}$ of Belle II collision data

Belle II Collaboration, F. Abudinén, I. Adachi +550

We present the first measurement of the time-integrated mixing probability $χ_{d}$ using Belle II data collected at a center-of-mass (CM) energy of 10.58 GeV, corresponding to the ma…

First search for direct $C P$ -violating asymmetry in $B^{0} \to K^{0} π^{0}$ decays at Belle II

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

We report on the first measurement of the direct $C P$ -violating asymmetry ( $A$ ) in the charmless decay $B^{0} \to K^{0} π^{0}$ at Belle II and an updated measurement of its bran…

Study of $B \to D^{(*)} h$ decays using $62.8 fb^{- 1}$ of Belle II data

Belle II Collaboration, F. Abudinen, I. Adachi +549

We report measurements related to hadronic $B$ decays to final states that contain charm mesons. The analyses are performed on a $62.8 fb^{- 1}$ data set collected by the B…
