MEASUREMENT OF THE STRONG COUPLING CONSTANT-ALPHA-S FROM A STUDY OF W BOSONS PRODUCED IN ASSOCIATION WITH JETS
- Abstract:
- The UA2 experiment at the CERN 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. © 1988.
