Dependence of the Rapidity Gap Correlations on the Multiplicity of Grey Particles

抄録

The characteristics of short-short and short-long rapidity gap correlations in 50GeV π ^--nucleus and 400, GeV proton-nucleus interactions have been investigated. Thedependence of the characteristics of clusters on the multiplicity of grey particles, N_g, has also been studied. The results reveal that the behaviour of the rapidity gap correlations and the average cluster size are not only independent of the size of the target nucleus but also do not depend on the identity and energy of the impinging hadron. However, the increasing value of the parameter R with increasing value of N_g and the energy of the projectile indicates the dominance of the short-short rapidity gap correlations over the short-long correlations.
