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.
