Description
The UA2 experiment at the CERN anti pp Collider has identified a total sample of 251 W → eν events. Among this sample 221 events are found without jets and 29 with one jet. The yield of one-jet events relative to that of zero-jet events provides a measurement of the strong coupling constant: αs(MW2) = 0.13±0.03(stat)±0.03(syst1)±0.02(syst2), where syst1 represents the experimental systematic error and syst2 is an estimate of the theoretical uncertainty.
