Fluctuation Studies at the Subnuclear Level of Matter: Evidence for Stability, Stationarity and Scaling
It is pointed out that the concepts and methods introduced by Bachelier and
by Mandelbrot to Finance and Economics can be used to examine the fluctuations
observed in high-energy hadron production processes. Theoretical arguments and
experimental evidences are presented which show that the relative variations of
hadron-numbers between successive rapidity intervals are non-Gaussian stable
random variables, which exhibit stationarity and scaling. The implications of
the obtained results are discussed.Comment: 34 Pages, 15 Postscript figures added references; corrected typos;
