Charm lifetime measurements at Belle II

We report precision measurements of lifetimes of charmed mesons and baryons performed by the Belle II experiment. Specifically, we measure $D_s^{+}$, $D^{+}$, $D^0$, ${\mathrm{\Lambda }}_c^{+}$, and ${\mathrm{\Omega }}_c^0$ lifetimes. Our results for $\tau (D_s^{+})$, $\tau (D^{+})$, $\tau (D^0)$, and $\tau ({\mathrm{\Lambda }}_c^{+})$ are the world’s most precise; our result for $\tau ({\mathrm{\Omega }}_c^0)$ confirms that the ${\mathrm{\Omega }}_c^0$ lifetime is longer than that of the ${\mathrm{\Lambda }}_c^{+}$ and the ${\mathrm{\Xi }}_c^0$.
