摘要: The UA2 experiment, running at the CERN SPS\(\bar pp\) Collider, has performed a study of events containing three hard jets in final state. angular distributions show evidence for gluon bremsstrahlung, good agreement with QCD model to leading order strong coupling constant αs. yield three-jet relative that two-jet provides measure constant: ;3K3/K2=0.23±0.01±0.04, whereK2 andK3 represent contributions arising from higher corrections α3 two- and exclusive cross-sections. A detailed discussion systematic theoretical uncertainties is given.
