Measurement of the Mass of the D0 Meson
The BABAR Collaboration
TL;DR
This paper reports a precise measurement of the D0 meson mass using specific decay channels with data from the BaBar detector, achieving half the uncertainty of previous measurements.
Contribution
The study provides the most precise D0 meson mass measurement to date, reducing the uncertainty by half compared to prior results.
Findings
Measured D0 mass as 1864.841 MeV
Achieved statistical and systematic uncertainties of 0.048 and 0.063 MeV
Improved precision over previous measurements
Abstract
We report a measurement of the D0 meson mass using the decay chain D*(2010)+ -> D0 pi+ with D0 -> K- K- K+ pi+. The data were recorded with the BaBar detector at center-of-mass energies at and near the Y(4S) resonance, and correspond to an integrated luminosity of approximately 477 1/fb. 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.
