Abstract

The Model of Quark–Gluon Strings is used for describing particle production at high energies. Cross-sections of large-mass diffractive production are described by the reggeon model where all legs of triple-reggeon and loop diagrams are eikonalized. Numerical calculation shows that this approach gives a very good description of available SS data on particle spectra in single diffractive dissociation process in a parameter-free way. Predictions of the model for particle spectra in non-single diffractive events are compared with data from SS and Tevatron and predictions for LHC are given.
