• It has been observed that the correlation coefficients <f_2>^- and <f_3>^- for the negative-prong multiplicity distribution in proton-proton collision, change sign around the incident momentum P_L 〜 50 GeV/c. On the other hand, the scaling limits of the specific moments <n^q_c> /<n_c>^q for the charged-prong multiplicity distribution have been found to increase rapidly with order q. It turned out that existing models cannot explain the above behavior. We present here a formula for the grand-partition function, which contains two functions F(ζ) and g (x) to be determined empirically. The function F(ζ) has turned out to be expressed most likely in terms of the hypergeometric function. The available data were not enough to determine the function g(x) in any reliable degree of accuracy. The experimental data of the correlation coefficients f^c_k for the charged-prong multiplicity distribution, can be used to check the proposed formula. The same formula can be applied to processed other than proton-proton collision.
