            We describe a measurement of charge-parity ( ) violation asymmetries in decays using Belle II data. We consider and decays. The data were collected at the SuperKEKB asymmetric-energy collider between the years 2019 and 2022, and contain bottom-antibottom meson pairs. We reconstruct signal decays and extract the violating parameters from a fit to the distribution of the proper-decay-time difference between the two mesons. The measured direct and mixing-induced asymmetries are and , respectively, where the first uncertainties are statistical and the second are systematic. These results are in agreement with current world averages and standard model predictions. Published by the American Physical Society2024more » « less
