Numerical modelling of Bose–Einstein correlations

We propose extension of the algorithm for numerical modelling of Bose–Einstein correlations (BEC), which was presented some time ago in the literature. It is formulated on quantum statistical level for a single event and uses the fact that identical particles subjected to Bose statistics do bunch themselves, in a maximal possible way, in the same cells in phase-space. The bunching effect is in our case obtained in novel way allowing for broad applications and fast numerical calculations. First comparison with e+e− annihilations data performed by using simple cascade hadronization model is very encouraging.
