摘要：
We have analysed our pn data at 400 GeV (corresponding to a centre-of-mass energy square-root s = 27.5 GeV) together with other pp and ppBAR data in the centre of mass energy range 11.5-900 GeV. The fits of all these distributions to a negative binomial distribution are performed. The variations in the fitted average multiplicity and in the inverse of the fitted parameter k are obtained with respect to the centre of mass energy. An assessment of the single diffractive component in the multiplicity distribution is made and its variation with the centre of mass energy discussed. The average number of clans and the average charged multiplicity per clan are determined and the centre of mass energy dependences shown.
