Time-dependent 𝑪𝑷 violation measurements at Belle II

We report the measurements of time-dependent 𝐶𝑃 violation at Belle II. The benchmark measurements of $𝐵^0$ lifetime (𝜏𝐵0 ) and mixing frequency (Δ𝑚𝑑) and time-dependent 𝐶𝑃 asymmetries in $𝐵^0$→ 𝐽/𝜓$𝐾_S^0$ have been performed using 190fb$^{−1}$. These measurements are statistically limited and show excellent detector performance and readiness for analysis setup. We also present the 𝐶𝑃 asymmetries in 𝑏 → $q\overline{ q }s$ transitions using 362fb$^{−1}$ which are very crucial to probe the effective value of sin $2𝜙_1$ and sensitive for new physics appearing through loops. All results agree with previous determinations and some of them are already competitive with the world’s best measurement.
