Extended sources, final state interactions and Bose-Einstein Correlations

II. Resonances and multiparticle rescattering

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

I extend the theory of Bose-Einstein correlations to the case where one of a pair of like pions is the daughter of resonance decay and include final state rescattering within the like pion pair. I consider critically the form of the isospin 2s-wave phase shift. The results of numerical calculations yield like pion correlation functions which are at best in marginal agreement with data frome + e − annihilation and proton-proton collisions. I show that the discrepancy which exists is removed by the effects of three (and more) particle rescattering. The quantitative interpretation of Bose-Einstein correlations among hadrons is very complicated unless the effective source size substantially exceeds 1 fm.
