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 π΅0 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 π΅0 β π½/Ξ¨πΎπ , π΅0 β πΎπ 0π0 and π΅0 β πΎπ 0πΎπ 0πΎπ 0 are reported.
