Query: A Position-Dependent Bose-Einstein Correlation Model for Hadronization
  Processes   Particles are either bosons or fermions, which obey Bose-Einstein (BE) or
Fermi-Dirac statistics, respectively. In the hadronization process the effects
of the former kind are the most important ones, since mesons are the most
common products in high-energy collisions. In the phenomenological Lund Model
the BE effect is approximated by a semiclassical momentum dependent correlation
function, which effectively acts as an attractive force between two mesons.
However, the Lund Model does also provide a space-time picture of the
hadronization process. Based on this, we have developed a simple extension of
the current LUBOEI algorithm that makes use of the production vertex distance
between two mesons.
  Comparisons between the old model and the new one is made for pions according
to exponential and Gaussian parameterizations of the BE correlation function.
Qualitatively we note a relative suppression of the BE effects in multi-jet
events, and especially for pairs of low momenta, with the new algorithm. This
trend is in agreement with preliminary experimental data.
