This paper presents a study of multiplicity distribution of the backward grey particles emitted in central 22 Ne–emulsion collisions at 4.1 AGeV/c using nuclear emulsion detectors. Applying the Heckman criteria in the present study central events of 22 Ne–emulsion collisions have been selected. Basic observables related to the multiplicity distribution including multiplicity moments, variance and the scaled variance have been calculated to characterize the shape of the multiplicity distribution quantitatively. This work attempts to model the backward grey particle multiplicity distribution using the Gamma distribution, Negative Binomial Distribution (NBD) and the KNO–type parametrization. In addition, a detailed analysis of Rényi and Shannon entropies has been carried out to gain further insight into the underlying multiplicity distribution.
