abstract = "We report a measurement of the parameter yCP in D0-D-0 oscillations performed by taking advantage of quantum coherence between pairs of D0D-0 mesons produced in e+e- annihilations near threshold. In this work, doubly-tagged D0D-0 events, where one D decays to a CP eigenstate and the other D decays in a semileptonic mode, are reconstructed using a data sample of 2.92 fb-1 collected with the BESIII detector at the center-of-mass energy of s=3.773 GeV. We obtain yCP=(-2.0±1.3±0.7)\%, where the first uncertainty is statistical and the second is systematic. This result is compatible with the current world average.",
