Measurement of the D[superscript *](2010)[superscript +] Meson Width and the D[superscript *](2010)[superscript +]-D[superscript 0] Mass Difference
We measure the mass difference Δm0 between the D[superscript *](2010)[superscript +] and the D[superscript 0] and the natural linewidth Γ of the transition D[superscript *](2010)[superscript +]→D[superscript 0]π[superscript +]. The data were recorded with the BABAR detector at center-of-mass energie...

| description | We measure the mass difference Δm0 between the D[superscript *](2010)[superscript +] and the D[superscript 0] and the natural linewidth Γ of the transition D[superscript *](2010)[superscript +]→D[superscript 0]π[superscript +]. 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[superscript -1]. The D[superscript 0] is reconstructed in the decay modes D[superscript 0]→K[superscript -]π[superscript +] and D[superscript 0]→K[superscript -]π[superscript +]π[superscript -]π[superscript +]. For the decay mode D[superscript 0]→K[superscript -]π[superscript +] we obtain Γ=(83.4±1.7±1.5) keV and Δm[subscript 0]=(145425.6±0.6±1.8) keV, where the quoted errors are statistical and systematic, respectively. For the D[superscript 0]→K[superscript -]π[superscript +]π[superscript -]π[superscript +] mode we obtain Γ=(83.2±1.5±2.6) keV and Δm[subscript 0]=(145426.6±0.5±2.0) keV. The combined measurements yield Γ=(83.3±1.2±1.4) keV and Δm[subscript 0]=(145425.9±0.4±1.7) keV; the width is a factor of approximately 12 times more precise than the previous value, while the mass difference is a factor of approximately 6 times more precise. |
