Abstract
Analysis of normalized C moments of multiplicity distribution calculated from the different phenomenological models, the Bialas-Praszalowics (BP) model, modified negative binomial and the superposed shifted Gompertz distribution at different center of mass (cms) energies is presented. The analysis covers a range of energies (200–900 GeV) of p¯p collisions in restricted phase space slices. A comparison of different models to the experimental data on charged particle multiplicity spectra from the 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 p¯p annihilation and pp interactions at the same center-of-mass energy are also presented.
