Search for Time-Dependent CP Violation in D0 →π+π-π0 Decays

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...
