Abstract

Analysis of normalised C-moments of multiplicity distribution calculated from the different phenomenological models, the Bialas-Praszalowics~(BP) model, modified negative binomial and the superposed SGD at different center of mass~(cms) energies is presented.~The analysis covers a range of energies~(200-900 GeV) of pˉp\bar{p}p collisions in restricted phase space slices.~A comparison of different models to the experimental data on charged particle multiplicity spectra from the pˉp\bar{p}p annihilation in five pseudorapidity windows is reported.~The comparison shows that the two approaches other than the BP model are in better agreement to the data.~Results on variation of moments with pseudorapidity window size and with center of mass energy and observations from such a study in pˉp\bar{p}p annihilation and pppp interactions at the same cms energy are also presented.
