Abstract

We measure the cross section for e(+)e(-)->psi(3770)-> hadrons at E-c.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(-)->psi(3770)-> D (D) over bar 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 Gamma(ee)(psi(3770))=(0.204 +/- 0.003(-0.027)(+0.041)) keV. Uncertainties shown are statistical and systematic, respectively.
