The data were recorded with the BABAR detector at center-of-mass energies at and near the ϒ(4S) resonance, and correspond to an integrated luminosity of approximately 477 fb⁻¹. We obtain m(D⁰)=(1864.841 ± 0.048 ± 0.063) MeV, where the quoted errors are statistical and systematic, respectively. The uncertainty of this measurement is half that of the best previous measurement.en-US©2013 American Physical SocietyD0 experimentMega electron volts (MeV)Mesons--MeasurementTextLees, J. P., V.
