A New Approach to Calculate Mean Charged Multiplicity For Proton – Nucleus Collisions Upto 1 TeV

The theoretical study of energy dependence of charged multiplicity could discriminate among the different theoretical models of particle production. In the present work, an attempt has been made to analyse the data on mean charged multiplicity in Hadron-Nucleus Collisions and also to modify the earlier parameterization with modified values of different parameters on the basis of some unambiguous phenomenon. The mean charged multiplicity has been calculated at different energies, ranging between 1.0 GeV to 1000 GeV for proton-nucleus collisions and the results are compared with experimental data as well as, with other theoretical results. Proposed parameterization is found to be capable of predicting the entire data.
