The first full angular analysis and an updated measurement of the decay-rate CP asymmetry of the D0 ??? x-+x-?????+????? and D0 ??? K+K?????+????? decays are reported. The analysis uses proton-proton collision data collected with the LHCb detector at center-of-mass energies of 7, 8, and 13 TeV. The dataset corresponds to an integrated luminosity of 9 fb???1. The full set of CP -averaged angular observables and their CP asymmetries are measured as a function of the dimuon invariant mass. The results are consistent with expectations from the standard model and with CP symmetry.

Abstract
The first full angular analysis and an updated measurement of the decay-rate CP asymmetry of the D0 ??? x-+x-?????+????? and D0 ??? K+K?????+????? decays are reported. The analysis uses proton-proton collision data collected with the LHCb detector at center-of-mass energies of 7, 8, and 13 TeV. The dataset corresponds to an integrated luminosity of 9 fb???1. The full set of CP -averaged angular observables and their CP asymmetries are measured as a function of the dimuon invariant mass. The results are consistent with expectations from the standard model and with CP symmetry.
