The data were recorded with the BABAR detector at center-of-mass energies at and near the (sic)(4S) resonance, and correspond to an integrated luminosity of approximately 468 fb(-1). We measure Delta m(+) = (140601.0 +/- 6.8[stat] +/- 12.9[syst]) keV. We combine this result with a previous BABAR measurement of Delta m(0) = m(D* (2010)(+)) -- m(D-0) to obtain Delta m(D) = m(D+) -- m(D-0) = (4824.9 +/- 6.8[stat] +/- 12.9[syst]) keV. These results are compatible with and approximately five times more precise than the Particle Data Group averages.", optnote="WOS:000415058400002", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=3362), last updated on Sat, 25 Nov 2017 20:12:16 +0000", issn="0031-9007", doi="10.1103/PhysRevLett.119.202003", opturl="http://arxiv.org/abs/1707.09328", opturl="https://doi.org/10.1103/PhysRevLett.119.202003", archivePrefix="arXiv", eprint="1707.09328", language="English" }
