Pseudorapidity and c.m. energy dependence of multiplicity distributions in hh collisions in the TeV region: new possible scenarios

Continuing previous work on the search for possible scenarios for multiparticle production mechanisms in hh collisions in the TeV energy region, it is assumed that the average charged multiplicity for the semihard component grows quadratically in the logarithm of c.m. energy and that the corresponding pseudorapidity plateau (dn/sub semihard//d eta ) grows logarithmically with c.m. energy. Consequences of these assumptions on the parameters used in order to describe the energy and pseudorapidity dependence of the resulting multiplicity distribution obtained by superimposing soft and semihard events components are explored. The multiplicity distribution of each class of events is chosen to be of Pascal type. (8 refs).
