“…The negative binomial distribution (NBD) has served as an especially accurate statistical model for a broad range of multiplicity observations in particle collision experiments, e.g. pp ¯, hh, hA, AA, e + e − [1][2][3][4][5] (See [6] for an overview), and is argued to be a scale-invariant property of matter [7,8], providing the best fit for astronomical observations, where it predicts the number of galaxies in a region of space [9][10][11][12]. Although several theories have been proposed to explain the relevance of the NBD, the precise physical principles behind its occurrence in these observations are unknown [1,2,11,13,14].…”
