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 𝐵0 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 𝐵0 → 𝐽/Ψ𝐾𝑠, 𝐵0 → 𝐾𝑠0𝜋0 and 𝐵0 → 𝐾𝑠0𝐾𝑠0𝐾𝑠0 are reported.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
