Correlations in the Multi-Regge model

An N-channel Chew-Pignotti model is formulated to calculate inclusive two-particle distributions. The connection with the Muller-Regge model is explicitely established in the central and fragmentation region. The shape of the correlation function is discussed qualitatively in all kinematic regions. One- and two-particle distributions for pp and π^?p interactions are calculated with parameters determined from a linear fit of $\text{?}{}_2\text{and}\text{〈n〉}$. The model is used to describe the pionization component in a two-component model.
