Short and Long Range Correlation of Hadrons in p Anti p Collisions at 540 GeV

摘要

Forward-Backward Multiplicity Correlations and Two-Particle Pseudorapidity Correlations are investigated in p anti p collisions at 540 GeV. The analysis in terms of a simple cluster approach yields values of ksub(eff) proportional 2.5 for the effective cluster size for the decay in charged particles and a decay width for the clusters of delta proportional 0.7 units in pseudorapidity. These values are almost unchanged when compared with those determined at ISR energies. (ERA citation 10:019354)
