In pp collisions at √ s = 44.7 and 62.3 GeV, where each proton fragments into at least one low- p T, high- x meson or baryon, no correlations between the particle momenta are found for ππ , π K, KK, and p π pairs. The ππ data show a preference for the formation of electrically neutral ππ systems. The KK data show the influence of strangeness conservation. For pp and pΛ final states, the momentum dependence of the correlation ratio R can be described by the scaling variable z = (1 − x 1 )(1 − x 2 ). Small deviations from factorization are discussed.

THE C (ALPHA, X) C-11 CROSS-SECTIONS AT 1.59-GEV AND 4.19-GEV

Geaga, J.V. ; Gazzaly, M.M. ; Igo, G.J. ; et al.
Nucl.Phys.A 386 (1982) 589-598, 1982.
Inspire Record 183652 DOI 10.17182/hepdata.37081

The absolute cross sections for the production of 11 C by 1.59 GeV and 4.19 GeV α-particles incident on natural carbon have been measured to be 46.4 ± 1.3 mb and 42.5 ± 1.1 mb respectively. These results, together with data reported at other energies, indicate that the C(α, X) 11 C cross section becomes approximately constant at a value of about 43 mb for energies above 3 GeV (750 MeV/n). A similar energy dependence is exhibited by the C(p, X) 11 C reaction whose cross section has been measured previously over an extensive energy range. The C(α, X) 11 C cross sections are found to be in good agreement with predictions of a semi-empirical model developed to describe nuclear fragmentation.

Dimuon Scaling Comparison at 44-{GeV} and 62-{GeV}

Antreasyan, D. ; Becker, U. ; Bellettini, G. ; et al.
Phys.Rev.Lett. 48 (1982) 302, 1982.
Inspire Record 168182 DOI 10.17182/hepdata.20610

Measurements of pp→μ+μ−+X at s=44 and 62 GeV are compared. The data are taken under identical conditions utilizing clean proton-proton collisions from the CERN intersecting storage rings and confirm scaling to 5%. The observed μ+μ− yield is a factor of 1.6±0.2 larger than estimated from a simple parton model but is consistent with QCD. The pT dependence of the muon pairs agrees well with expectations from QCD.
