Abstract:

We measure the cross section for e+e-→ψ(3770)→hadrons at Ec.m.=3773MeV to be (6.38±0.08-0.30+0.41)nb using the CLEO detector at the CESR e+e- collider. The difference between this and the e+e- →ψ(3770)→DD̄ cross section at the same energy is found to be (-0.01±0.08-0.30+0.41)nb. With the observed total cross section, we extract Γee(ψ(3770))=(0.204±0.003-0.027+0.041)keV. Uncertainties shown are statistical and systematic, respectively. © 2006 The American Physical Society.

Abstract:

We report on precision measurements of the masses and widths of the narrow, orbitally excited states D10 and D2*0 using the CDF II detector at the Fermilab Tevatron. Both states (collectively called D**) are reconstructed in the decay channel D**→D*+π-. The D2*0 is also reconstructed in the D**→D+π- channel. Using a data set with an integrated luminosity of 210pb-1, the measured masses and widths for the D10 are 2421.7±0.7±0.6 MeV/c2 and 20.0±1.7±1.3 MeV/c2 respectively, while for the D2*0 they are 2463.3±0.6±0.8 MeV/c2 and 49.2±2.3±1.2 MeV/c2. These values are currently the single best measurements available. © 2006 The American Physical Society.
