Description

We measure the cross section for e+e-→ψ(3770)→hadrons at Ec.m.=3773 MeV 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)→DD 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
