Study of negative binomial distribution in charged-current neutrino–lead interactions

The negative binomial distribution is an statistical distribution which has been applied in many interactions and its validity to describe the charged particle multiplicity distribution has been reported. In this paper, charged hadron multiplicity distributions produced in neutrino–lead interactions of OPERA experiment are analyzed in terms of the negative binomial distribution for different W2\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$W^{2}$$\end{document} intervals. The compatibility of the data with the applied fit is observed in each energy range and the energy dependence of the free parameters is presented.
