Bose-Einstein correlations
Description
Two quite different but interconnected topics are covered: the Bose-Einstein effect in two-jet events at LEP, i.e. events with a single string structure, and a new test on hydrodynamical models. In this test the interferometrical correlator plays a key role and can be used to bring information on the matter evolution in time and space. A preliminary DELPHI analysis has however shown that the extraction of the two-particle correlation function is contaminated by large systematic uncertainties. Three different analysis, all using standard methods, give inconsistent results. Furthermore the two-particle correlation itself is shown to be due not only to Bose-Einstein correlations but also to the decay of heavy quark resonances, so the determination of the Bose-Einstein effect depends on the modelling of these other sources. This modelling is at the moment not accurate enough. More work is needed to clarify the situation. (author) 25 refs.; 16 figs.; 1 tab
