The data were recorded with the BABAR detector at center-of-mass energies at and near the Υ ( 4 S ) resonance, and correspond to an integrated luminosity of approximately 477 fb − 1 . We obtain m ( D 0 ) = ( 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.7 p.application/pdfeng(c) American Physical Society, 2013Física de partículesExperimentsMesons (Física nuclear)Massa (Física)Particle physicsExperimentsMesons (Nuclear physics)Mass (Physics)Measurement of the mass of the D0 mesoninfo:eu-repo/semantics/article6316462019-04-08info:eu-repo/semantics/openAccess
