Three-jet events at the CERN intersecting storage rings
Nuclear Physics, Section B 303:4 (1988) 569-606
Abstract:
Three-jet events have been observed in pp collisions at s = 62.3 GeV. The data were collected using a total neutral energy trigger with a threshold at 25 GeV. These events appear predominantly as two jets, with some appearing as three jets. A novel analysis for the extraction of 2-jet and 3-jet events is described, and some of the event properties are discussed. The relative numbers of two- and three-jet events are studied within the framework of leading-order QCD, and yield a value of αs(K3/K2) = 0.19 ± 0.02 (stat.) ± 0.04 (syst.). © 1988.3-JET EVENTS AT THE CERN INTERSECTING STORAGE-RINGS

Observation of KNO scaling in the neutral energy spectra from αα and pp collisions at ISR energies
Physics Letters B 168:1-2 (1986) 158-162
Abstract:
Neutral transverse energy spectra in pp and αα interactions are analyzed in terms of the wounded nucleon model. Analysis of the αα spectrum by application of a multiple nucleon-nucleon collision mechanism is conveniently performed when a gamma distribution is used to represent the pp spectral shape. The wounded nucleon model provides a reasonable description of the αα spectrum for the first three orders of magnitude, but completly fails to account for the slope of the high energy tail of the distribution. However, the pp and αα spectra can both be fitted to the same gamma distribution when scaled by their respective mean values and thus exhibit KNO scaling. © 1986.High transverse energy and high transverse momentum events in pp and pp interactions at the CERN intersecting storage rings
