Universal Mass Dependence of Final Hadron Yields in High Energy Reactions

  • Recently experiments found that multiplicities of final state particles in high energy reactions and their masses satisfy a simple universal experienced formula. In this paper the multiplicities of directly producted mesons and baryons in e+e annihilation and pp(p) reaction are calculated and are in complete agreement with the parameter in the experienced formula. And we can give a reasonable interpretation of parameters that are relevant to energy. The reasons of the mass universal relation are discussed.

Abstract: Recently experiments found that multiplicities of final state particles in high energy reactions and their masses satisfy a simple universal experienced formula. In this paper the multiplicities of directly producted mesons and baryons in e+e annihilation and pp(p) reaction are calculated and are in complete agreement with the parameter in the experienced formula. And we can give a reasonable interpretation of parameters that are relevant to energy. The reasons of the mass universal relation are discussed.
