Analysis of Experimental Semi-Inclusive Distributions at the SPS-Collider Energies

The experimental data on hadron-hadron interactions at high up to SPS-collider energies are analysed carefully within a multicomponent approach based on the renormalization group method. In particular, the behaviour of total cross sections and forward-backward correlations of scattered particles is described as well as the broadening of p_T-spectra with increasing multiplicity of charged particles and the “sea-gull” effect for η-distributions observed at small multiplicities.
