Measurement of the branching fractions and $C P$ asymmetries of $B^{+} \to π^{+} π^{0}$ and $B^{+} \to K^{+} π^{0}$ decays in 2019-2021 Belle II data

Belle II Collaboration, F. Abudinén, I. Adachi +582

We determine the branching fractions $B$ and $C P$ asymmetries $A_{CP}$ of the decays $B^{+} \to π^{+} π^{0}$ and $B^{+} \to K^{+} π^{0}$ . The result…

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…
