| Description: |
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: m ( K S 0 π 0 ) ∈ ( 0.8 , 1.0 ) GeV / c 2 , which is dominated by B0→K*0(→KS0π0)γ decays, and a complementary region m(KS0π0 |
