Abstract
A measurement of time-dependent CP violation in D0→π+π-π0 decays using a pp collision data sample collected by the LHCb experiment in 2012 and from 2015 to 2018, corresponding to an integrated luminosity of 7.7 fb-1, is presented. The initial flavor of each D0 candidate is determined from the charge of the pion produced in the D∗(2010)+→D0π+ decay. The decay D0→K-π+π0 is used as a control channel to validate the measurement procedure. The gradient of the time-dependent CP asymmetry ΔY in D0→π+π-π0 decays is measured to be ΔY=(-1.3±6.3±2.4)×10-4, where the first uncertainty is statistical and the second is systematic, which is compatible with CP conservation.
