Search for $$CP$$ violation in the $$D^{+}topi^{+}pi^{0}$$ decay at Belle

Babu, V.*; Tanida, Kiyoshi   ; Belle Collaboration*; 197 of others*

We search for $$CP$$ violation in the charged charm meson decay $$D^{+}topi^{+}pi^{0}$$, based on a data sample corresponding to an integrated luminosity of $$rm 921~fb^{-1}$$ collected by the Belle experiment at the KEKB $$e^{+}e^{-}$$ asymmetric-energy collider. The measured $$CP$$ violating asymmetry is $$[+2.31pm1.24({rm stat})pm0.23({rm syst})]%$$, which is consistent with the standard model prediction and has a significantly improved precision compared to previous results.
