We present a measurement of the cross section for hadron production by e+e− annihilation in the vicinity of the previously observed resonance near 3.77 GeV. The data are used to determine the parameters of the ψ(3770) resonance. The values found are: mass, 3764±5 MeV/c2, total width, 23.5±5 MeV, and partial width to electron pairs, 276±50 eV.

Search for Narrow Resonances in e+ e- Annihilation Into Hadrons at ADONE

Bartoli, B. ; Bisello, D. ; Esposito, B. ; et al.
Phys.Lett.B 58 (1975) 478-480, 1975.
Inspire Record 100116 DOI 10.17182/hepdata.27782

A search for narrow resonances in the reaction e + e − → hadrons in the mass regions 1915–2345 MeV and 2970–3090 MeV has been perforned at ADONE, the Frascati storage ring. With 90% confidence level our data exclude the production of narrow resonances with integrated cross section larger than 20% of the integrated cross section for production of the J/Ψ (3100 MeV).
