Neutral kaon production in K+ p and pi+ p interactions at 250-GeV/c

The EHS/NA22 collaboration Ajinenko, I.V. ; Albert, L. ; Belokopytov, Yu. A. ; et al.
Z.Phys.C 46 (1990) 525-536, 1990.
Inspire Record 302184 DOI 10.17182/hepdata.15191

The inclusive production of neutral kaons is studied inK+p and π+p interactions at 250 GeV/c. Total and semi-inclusive cross sections and average kaon multiplicities are presented and compared with the data at lower energies. The longitudinal and transverse momentum distributions and their energy dependence are analyzed. The results are interpreted in the framework of recent parton models.

Inclusive production of vector mesons in pi+ p interactions at 250-GeV/c

The EHS/NA22 collaboration Agababyan, N.M. ; Ajinenko, I.V. ; Belokopytov, Yu. A. ; et al.
Z.Phys.C 46 (1990) 387-395, 1990.
Inspire Record 301243 DOI 10.17182/hepdata.15240

We report on a study of ρ0, ρ+, ω,\(\bar K^{*0} (892)\) andK*0 (892) inclusive production in π+p interactions at 250 GeV/c, for ρ+,\(\bar K^{*0} (892)\) for the first time in a π+p experiment. The data are compared withK+p data in the same experiment, with results of other experiments and with quark-parton models. Interesting differences are found between ρ+,0 and ω production.

Measurement of Jet Production Properties at the CERN anti-p p Collider

The UA2 & Bern-CERN-Copenhagen-Orsay-Pavia-Saclay collaborations Bagnaia, P. ; Banner, M. ; Battiston, R. ; et al.
Phys.Lett.B 144 (1984) 283-290, 1984.
Inspire Record 202658 DOI 10.17182/hepdata.30516

Jet production properties at s = 540 GeV have been measured in the UA2 detector at the CERN p p Collider. Results on the total transverse momentum of the jet system, on the parton density in the nucleon (structure function) and on the two-jet angular distributions are reported. The data are compared with QCD predictions and extrapolations from lower energy experiments.

Angular Distributions and Structure Functions from Two Jet Events at the CERN SPS $p \bar{p}$ Collider

The UA1 collaboration Arnison, G. ; Astbury, A. ; Aubert, Bernard ; et al.
Phys.Lett.B 136 (1984) 294-300, 1984.
Inspire Record 195946 DOI 10.17182/hepdata.30581

The two-jet cross section measured in the UA1 apparatus at the CERN p p Collider has been analysed in terms of the centre-of-mass scattering angle θ and the scaled longitudinal parton momenta x 1 and x 2 . The angular distribution d σ /d cos σ rises rapidly as cos → 1, independent of x 2 and x 2 , as expected in vector gluon theories (QCD). The differential cross section in x 1 and x 2 is consistent with factorization and provides a measurement of the proton structure function F(x) = G(x) + 4 9 [Q(x) + Q (x)] at values of the four-momentum transfer squared, -t̂ ≈ 2000 GeV 2 . Over the range x = 0.10−0.80 the structure function shows an exponential x dependence and may be parametrized by the form F ( x ) = 6.2 exp (−9.5 x ).
