Bose-Einstein correlations from “within”

Abstract

Abstract. We describe an attempt to model numerically Bose-Einstein correlations (BEC) from "within", i.e., by using them as the most fundamental ingredient of some Monte Carlo event generator (MC) rather than considering them as a kind of (more or less important, depending on the actual situation) "afterburner", which inevitably changes original physical content of the MC code used to model multiparticle production process. Introduction. The problem of BEC is so well known that we shall skip introductory remarks (referring in that matter to other presentations at this conference and to [1] for more information) and instead we shall start right away with our subject concerning the proper numerical modelling of BEC, which we call BEC from within. Although phenomenon of BEC is with us from the very beginning of the systematic investigation of multiparticle production processes, its modelling is still virtually nonexisting. With the exception of attempts presented in [2,3] all other approaches are tacitly assuming that on the whole BEC constitute only a small effect and it is therefore justify to add it in some way to the already known outputs of the MC event generators widely used to model results of high energy collisions (in the form of the so called afterburner) 1 . There are two types of such afterburners: Keywords
