Modeling of quantum effects in the hadronization

A recent observation of a threshold momentum difference in the production of adjacent hadrons is implemented in the fragmentation model of a three-dimensional QCD string, with the aim to investigate the common origin of the azimuthal ordering of hadrons and of the correlations commonly attributed to the Bose-Einstein effect. The role of particle decays and their polarization in the measurement of two-particle correlations is evaluated. A comparison with the available data is presented and further measurements suggested. The impact of the hadronization on the long range angular correlations is discussed.

Inter-W Bose-Einstein Correlations ... or Not?

A critical summary is given of the present status of the study of Bose-Einstein Correlations in W-pair production at LEP II. In particular, the evidence is reviewed for or against the existence of Bose-Einstein correlations between pions originating both from a different of the two W's. If present, such an inter-W interference would not only form a potential bias in the determination of the W mass, but also would provide a laboratory to measure the space-time development of the overlap. If absent, this would drastically change the conventional (Hanbury Brown and Twiss) picture of pion interferometry in high energy physics.
