Abstract: (APS)
We report measurements of time-dependent asymmetries in decays based on a data sample of events collected at the resonance with the Belle II detector. The Belle II experiment operates at the SuperKEKB asymmetric-energy collider. We measure decay-time distributions to determine -violating parameters and . We determine these parameters for two ranges of invariant mass: , which is dominated by decays, and a complementary region . Our results have improved precision as compared to previous measurements and are consistent with theory predictions.Note:
