AbstractAbstract
[en] Analyzing the data recorded with the MD-1 detector operated at the VEPP-4 storage ring we have determined the Υ(1S) resonance leptonic partial width and mass. We find Γee=1.29±0.03±0.03 keV, M=9460.59±0.09±0.05 MeV/c2. This new value of the Υ(1S) mass should supersede the previously published value [11] based on almost the same statistics. (orig.)
