摘要：

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