Description

The charged particle multiplicity distribution is studied for non-single-diffractive π+p collisions at √S = 22 GeV, in central rapidity intervals separated from the outer regions by empty gaps. A priori unexpectedly, also these distributions yield good negative binomial fits. The variation of the parameter 1/k as a function of the gap size can be understood in terms of cascading clans of limited rapidity range if events with a large number of clans preferably contribute to the central region. The Fritiof-3 model agrees quantitatively with the data. (orig.)
