On the Multiplicity Distributions of Charged Secondaries in the Collisions of Relativistic Nuclei

Multiplicities of charged secondary hadrons in the relativistic nucleus-nucleus collisions in a wide energy range are analysed on the basis of partial stimul- ting emission and cluster cascading models. The experimental data are obtained by means of the two metre propane bubble chamber of JINR (Dubna). The results are compared with the correponding data for pp and anti pp-colli- sions at higher energies. It is shown that the regularities in pp and anti pp- interactions at high energies and wide energy range and in nucleus-nucleus interactions at relatively low energies per nucleon and narrower energy range are similar.

Towards the Light Front Variables for High Energy Production Processes

Scale invariant presentation of inclusive spectra in terms of light front variables is proposed. The variables introduced go over to the well-known scaling variables x_F = 2p_z/sqrt(s) and x_T=2p_T/sqrt{s} in the high p_z and high p_T limits respectively. So Some surface is found in the phase space of produced pi-mesons in the inclusive reaction anti p p -> pi+- X at 22.4 GeV/c, which separates two groups of particles with significantly different characteristics. In one of these regions a naive statistical model seems to be in a good agreement with data, whereas it fails in the second region. Key words: Light front, inclusive, hadron-hadron, electron-positron, relativistic heavy ions, deep inelastic.
