Measurement of the $CP$ asymmetry in $D^0\to {\pi }^{+}{\pi }^{-}{\pi }^0$ decays at Belle II

Belle II Collaboration, M. Abumusabh, I. Adachi +400

We measure the time- and phase-space-integrated $CP$ asymmetry $A_{CP}$ in $D^0\to {\pi }^{+}{\pi }^{-}{\pi }^0$ decays reconstructed in $e^{+}{e}^{-}\to c\bar{c}$ events collected by the Belle II experiment…
