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

Abstract:
The multiplicity of particles associated with electron pairs with mass greater than 11 GeV/c2 is found to increase with the transverse momentum pT of the electron pair. The associated particles are observed to recoil against the electron pair and compensate locally its transverse momentum. The data are compared with lower √s dimuon data using the scaling form: s2pT2(d3 σ/dy dpT2 dm2) = H (xT, y, τ). © 1984.A study of e+e- pairs in the mass range 11 to 25 GeV/c2 at the CERN intersecting storage rings

Abstract:
A sample of 58e+e- events with an invariant mass greater than 11 GeV/c2 produced in pp collisions at a centre-of-mass energy of 62.3 GeV is discussed. The cross sections are presented as a function of the mass and transverse momentum.
