Neutral Particle Production in pi+ p and p p Collisions at 100-GeV/c

Alston-Garnjost, Margaret ; Erwin, J. ; Klems, J.H. ; et al.
Phys.Rev.Lett. 35 (1975) 142, 1975.
Inspire Record 98682 DOI 10.17182/hepdata.21191

We have measured the inclusive cross sections for γ, Ks0, Λ, and Λ¯ production in π+p and pp interactions at 100 GeV/c and compared various inclusive distributions of the produced γ and Ks0.

Measurement of the Dijet Cross-Section in 400-GeV p p Collisions

The E-609 collaboration Arenton, M.W. ; Ditzler, W.R. ; Fields, T.H. ; et al.
Phys.Rev.Lett. 53 (1984) 1988, 1984.
Inspire Record 15116 DOI 10.17182/hepdata.23566

The invariant cross section for production of jet pairs in 400-GeV/c pp interactions has been measured as a function of pT in the pT range 4 to 9 GeV/c. The results are in good agreement with predictions of perturbative QCD models.

Differential cross sections of J/psi and psi' in 800-GeV/c p Si interactions.

The E-771 collaboration Alexopoulos, T. ; Durandet, C. ; Erwin, A.R. ; et al.
Phys.Rev.D 55 (1997) 3927-3932, 1997.
Inspire Record 446872 DOI 10.17182/hepdata.22271

We present the xF and pT differential cross sections of J/ψ and ψ′, respectively, in the ranges −0.05<xF<0.25 and pT<3.5 GeV/c. The data samples are constituted by about 12 000 J/ψ and 200 ψ′ produced in proton-silicon interactions at 800 GeV/c and decaying into opposite sign muons. The xF and pT distributions are compared with recent results from experiments E789 at the same energy and to leading order QCD predictions using the MRS D0 parametrization for the parton structure function. The measured shapes of the differential cross sections, except for the dσ/dxF at small xF, agree very well with the prediction, even though their value is quite a bit larger than the prediction. We also present the cosθ differential cross section of the J/ψ which indicates unpolarized production in contrast with color octet models predictions.
