Abstract

The data recorded with the MD-1 detector operated at the VEPP-4 storage ring were analyzed and the {Upsilon}(1s) resonance leptonic partial width and mass are determined. {Gamma}{sub ee}=1.29+-0.03+-0.03 keV, M=9460.59+-0.09+-0.05 MeV/c{sup 2} are find. Thies new value of the {Upsilon}(1s) nass should superside the previously published value. 26 refs.; 6 figs.; 1 tab.
