Abstract

The large sample of W→ev events collected by the UA2 experiment at the CERN pp̄ collider between 1988 and 1990 has been used to determine the strong coupling constant α s. From a measurement of the ratio of the production rate of W events with one jet to that with no jets, α s has been extracted to second order in the MS scheme: α s (M W 2) = 0.123 ± 0.0.18 (stat.) ± 0.017 (syst.).
