Abstract
Measurements of decay-time-dependent CP violation are chief goals of the Belle II physics program. These kind of measurements are sensitive probes of non-SM physics. This talk presents first Belle II results on the mixing rate and lifetime of 𝐡0 mesons, an essential validation of time- dependent measurements that requires detailed control of complex high-level capabilities such as flavor tagging and decay-time resolution modeling. Recent results on 𝐡0 β†’ 𝐽/Ψ𝐾𝑠, 𝐡0 β†’ 𝐾𝑠0πœ‹0 and 𝐡0 β†’ 𝐾𝑠0𝐾𝑠0𝐾𝑠0 are reported.
