Abstract

A measurement of time-dependent CP violation in D0?p+p-p0 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)+?D0p+ decay. The decay D0?K-p+p0 is used as a control channel to validate the measurement procedure. The gradient of the time-dependent CP asymmetry ?Y in D0?p+p-p0 decays is measured to be ?Y=(-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.
