Title: Search for C P violation in the D + π + π 0 decay at Belle

Abstract

We search for CP violation in the charged charm meson decay D+ → π+π0, based on a data sample corresponding to an integrated luminosity of 921 fb-1 collected by the Belle experiment at the KEKB eþe- asymmetric-energy collider. The measured CP-violating asymmetry is [+2.31±1.24(stat) ± 0.23(syst)]%, which is consistent with the standard model prediction and has a significantly improved precision compared to previous results.
