The role of double parton collisions in soft hadron interactions

Abstract We have examined charged multiplicities arising from p−p and p− p collisions over the range of center of mass energies, s , from 30 GeV to 1800 GeV. Results from Tevatron experiment E735 support the presence of double parton interactions. These processes can be seen to account for a large fraction of the increase in the non single diffraction inelastic cross section from energies of about 200 GeV to 1800 GeV.

Charged particle multiplicity correlations in pp̄ collisions at s=0.3−1.8 TeV

Abstract The correlations between charged particle multiplicitie produced in forward and backward pseudorapidity regions in pp interactions have been measured with a 240 element scintillator hodoscope. The correlation coefficient and the variance of the difference of multiplicities in the two pseudorapidity regions were deterermined for s =0.3−1.8 TeV . These results have been interpreted in terms of a cluster model of particle production.

Abstract A plastic scintillator hodoscope for an experiment at the Fermilab Tevatron proton-antiproton collider is described. The hodoscope is used on-line to form a charged multiplicity trigger and off-line to study charged particle multiplicity distributions. The hodoscope consists of 240 counters covering the pseudorapidity range of ±3.25. It is designed to survive a radiation dose of up to 100 krad over the experiments lifetime.

Abstract Four types of scintillator were subjected to background radiation in the Tevatron accelerator tunnel. Light output was reduced for doses above 15 krad.

\sqrt{s}

Abstract We present a survey of the recent results of E-735 in its search for QGP signals at the Fermilab Collider. The basic data are the inclusive P t distributions of centrally produced π, K, p and Λ 0 as a function of total charged multiplicity in the collision; the variation of 〈P t 〉 and particle ratios are derived. Preliminary results on π-π correlations and inclusive photon production are also presented.

Feed forward neural networks have been trained, using back‐propagation, to find the slopes of simulated track segments in a straw chamber and to find the vertex of tracks from both simulated and real events in a more conventional drift chamber geometry. Network architectures, training, and performance are presented.
