F. Abe et al., FURTHER PROPERTIES OF HIGH-MASS MULTIJET EVENTS AT THE FERMILAB PROTON-ANTIPROTON COLLIDER, Physical review. D. Particles and fields, 54(7), 1996, pp. 4221-4233
The properties of high-mass multijet events produced at the Fermilab p
roton-antiproton collider are compared with leading order QCD matrix e
lement predictions, QCD parton shower Monte Carlo predictions, and the
predictions from a model in which events are distributed uniformly ov
er the available multibody phase space. Multijet distributions corresp
onding to (4N-4) variables that span the N-body parameter space are fo
und to be well described by the QCD calculations for inclusive three-j
et, four-jet, and five-jet events. The agreement between data, QCD mat
rix element calculations, and QCD parton shower Monte Carlo prediction
s suggests that 2-->2 scattering plus gluon radiation provides a good
first approximation to the full LO QCD matrix element for events with
three, four, or even five jets in the final state.
