Precise measurement of the $D^0$ and $D^{+}$ lifetimes at Belle II

Belle II collaboration, F. Abudinén, I. Adachi +385

We report a measurement of the $D^0$ and $D^{+}$ lifetimes using $D^0\to K^{-}{\pi }^{+}$ and $D^{+}\to K^{-}{\pi }^{+}{\pi }^{+}$ decays reconstructed in $e^{+}{e}^{-}\to c\bar{c}$ data recorded by the Belle II exp…
