Factorial Correlators (FCs), a tool for the test of “intermittency” in multiparticle production in high energy physics, has not been given much attention, compared to the efforts towards understanding the phenomenon in terms of scaled factorial moments. So far, only hadron-hadron data of NA22 collaboration and nucleus-nucleus data of EMU01 collaboration have been analyzed in terms of FCs. However, the present situation of intermittency study demands thorough exploitation of all the available tools for better understanding of the phenomenon. In this article we present the analysis of particle production data of hadron-nucleus interaction at 200 GeV/c in terms of FCs. The results of the analysis show a consistency with the prediction of α-model for the existence of “intermittency.”

The Feynman diagram generator FeynArts and the computer algebra program FormCalc allow for an automatic computation of 2→2 and 2→3 scattering processes in High Energy Physics. We have extended this package by four new kinematical routines and adapted one existing routine in order to accomodate also two- and three-body decays of massive particles. This makes it possible to compute automatically two- and three-body particle decay widths and decay energy distributions as well as resonant particle production within the Standard Model and the Minimal Supersymmetric Standard Model at the tree- and loop-level. The use of the program is illustrated with three standard examples: [Formula: see text], [Formula: see text], and [Formula: see text].
