Abstract

In an experiment with the 30-inch Hybrid Spectrometer at Fermilab we have obtained the inclusive and semi-inclusive production cross sections of the ϱ0 meson using a conventional background subtraction technique. Production cross sections for the ϱ0 are derived as a function of the Feynman scaling variablex, and the transverse variablespt2 andEt=(pt2+M2)1/2. The longitudinal distributions are compared with the (1−x) dependence of the proton and meson valence quark structure functions, using various forms of recombination and fragmentation models. The transverse distributions are compared with thermodynamic models. We give density matrix elements for the ϱ0 production from pions in the extreme forward region.

Abstract

The ratio of hadronic p+/p- production has been studied in the target fragmentation region of p+p, p-p,K+p andp p collisions at 147 GeV/c beam momentum. The difference between this ratio in the p+p and p-p data is less than at lower energies but still present. No difference exists anymore for the p+/p- ratio at this energy betweenK+p andpp collisions. Exclusion of diffraction dissociation and resonance production does not change the main conclusions. The energy dependence of the ratio for p+p and p-p collisions gives evidence for a universal asymptotic ratio for all beams. Thept-dependence at low-pt is in agreement with the expectation from geometrical correlation of the valence quarks.

Abstract

We have studied the reactionspp?ppp+p-,K+p?K+pp+p-p, p+p? p+,pp+p- and p-p ?p+p- at 147 GeV/c using the 30-inch Fermilab hybrid system. All four reactions were detected with the same apparatus and analyzed in the same way. The energy dependence of the channel cross section was found to beAp-0.6+B for thepp reaction andAp-1+B for the other three. About 90% of the cross section at 147 GeV/c can be accounted for by either beam or target diffraction. Some of the remaining cross section may come from double Pomeron exchange reactions which we tried to isolate. We have tested the hypothesis of a factorizable Pomeron and our data indicates a violation of this hypothesis. We show that the 3p mass enhancement in the mass region 1.2–1.4 GeV is diffractively produced in the p± beam reactions. Fourprong, four-constraint and six-prong, four-constraint cross sections are reported.

Abstract

The gross features of the data are reviewed and the momentum tensor components, , and are studied. Evidence for coplanarity effects is observed. A probabilistic method to search for jets is proposed. The jets found by this method are seen to be similar to highpT jets frompp interactionse+e- annihilations andvp interactions. The effect of subtracting the leading particles and the effect of lowpT diffractive and non diffractive components are investigated.

Abstract

Distributions with respect toz andzR for the fastest and second fastest particles produced in both beam and target hemispheres from 147 GeV/c p- interactions are compared with each other and with the distributions for the fastest and second fastest particles from deepinelastic leptoproduction and Field-Feynman curves. The distributions and curves for the fastest particles are very similar, with the exception of the identified protons. Those for the second fastest are in agreement. Distributions with respect toz'R for the first through fourth fastest particles (excepting the protons) are all similar, suggesting that the shape of the distributions may be determined by the available longitudinal phase space.
