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.

Transverse momentum spectra of charged particles produced within the pseudo-rapidity range of η= − 0.36 to + 1.0 have been measured in pp collisions at √s=0.3, 0.54, 1.0, and 1.8 TeV. The spectra are presented as a function of event charged multiplicity within the range −3.25<η<3.25. We found that the slope in the low pt region is independent of center-of-mass energy and multiplicity while the slope at the high pt region shows a strong energy and multiplicity dependence.

Abstract The construction and operation of a 2 m long cylindrical drift chamber used as a high-multiplicity charged-particle detector at the Fermilab Tevatron collider is presented. The chamber was constructed of low-mass carbon fibe-epoxy composite material and presents 0.014 interaction lengths of material to particles passing radially through it. A 24-layer “jet”-type drift cell was used which obtained a spatial resolution of 250 μm and a two-hit separation of 3 mm. The chamber reconstructed events containing more than 100 charged particles over approximately 3.4 units of pseudorapidity.
