EXPERIMENTAL REGULARITIES IN PARTICLE PRODUCTION RATES AND IN MULTIPLICITY DISTRIBUTIONS FOR e+e- AND p±p COLLISIONS

摘要

It is shown that production rates of the pseudoscalar and vector mesons (apart from pions) and, octet and decuplet baryons, weighted with the spin and isospin counting factors, are described as a function of their masses squared by a simple exponential exp(-(M/6)2). The relative production rates of these particles are independent of energy and practically the same for e+e~ and pp collisions (for particles not resulting from fragmentation of incident protons). These regularities are reflected in behaviour of the charged particle multiplicity distributions in e+e~ and p±p collisions.
