Universal Mass Dependence of Directly Produced Hadron Rates

  • In virtue of the simple physical picture of quark combination model and the probability for the production of a qfqf of a flavor f which is given by treating the pair creation of the qq as a quantum mechanical tunneling effect, an universal mass relation for direct hadron production rates, =Aexp(-bm), is obtained without any additional assumption. It is satisfied by various high energy reactions. This universal mass relation is in agreement with a simple empirical regulation proposed recently and is independent of the mass-center energy and the process of the reactions. This suggests that the mass of hadrons is the primary factor for describing the particle multiplicities.

Universal Mass Dependence of Directly Produced Hadron Rates

Abstract: In virtue of the simple physical picture of quark combination model and the probability for the production of a qfqf of a flavor f which is given by treating the pair creation of the qq as a quantum mechanical tunneling effect, an universal mass relation for direct hadron production rates, =Aexp(-bm), is obtained without any additional assumption. It is satisfied by various high energy reactions. This universal mass relation is in agreement with a simple empirical regulation proposed recently and is independent of the mass-center energy and the process of the reactions. This suggests that the mass of hadrons is the primary factor for describing the particle multiplicities.
