摘要：

The strong coupling constant alpha(s) has been determined from a study of the reaction ppBAR --> W +/- X, W --> ev at square-root s of 630 GeV in the UA 1 experiment at CERN. The measurement is based upon a study of jet production in association with W bosons. The result obtained is alpha(s)(M(W)2) = 0.127 +/- 0.026(stat) +/- 0.034(syst).
