Measurement of the strong coupling constant αs from a study of W Bosons produced in association with jets
Physics Letters B 215:1 (1988) 175-185
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.Direct photon production in {Mathematical expression} in collisions at {Mathematical expression} GeV
Zeitschrift für Physik C Particles and Fields 41:3 (1988) 395-404
Abstract:
A measurement of the direct production of photons with high transverse momentum from {Mathematical expression} collisions at {Mathematical expression} GeV is presented. The structure of events containing a high transverse momentum photon is studied. The results support predictions from QCD theory. © 1988 Springer-Verlag.DIRECT PHOTON PRODUCTION IN PBARP COLLISIONS AT SQUARE-ROOT-S=630 GEV
