Abstract:
The energy dependence of the average of the charged multiplicity and its dispersion in π+/K+/p interaction on protons at 147 GeV/c is found to be the same as in e+e- annihilations if an "effective energy" variable is used instead of the total energy. The effective energy Seff is defined as the invariant mass of all secondaries left after the two leading particles have been removed. Fitting the expression aSeffb to the average charge multiplicity 〈nch〉, we find the power b to be in good agreement with the value of 0.25 predicted by Fermi's statistical model and by Landau's hydrodynamical model. © 1981.
