  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.
