A field theoretic cluster model of multiperipheral production

A field theoretic cluster model of multiproduction process in hadron-hadron collisions at high energy is considered. The multiproduction here is a two-step process. In the first step clusters are produced. We use a field theoretic formalism to describe cluster creation. A validity of the standard approximations, that are usually made in multiperipheral models is discussed. A modified strong ordering hypothesis is proposed. This leads to the Feynman scaling violation. Then cluster decay is considered. Expressions for semi-inclusive pion distributions in rapidity are given and a comparison with experimental data is made.
