Proposition of numerical modelling of BEC

We propose extension of the numerical method to model effect of Bose-Einstein correlations (BEC) observed in hadronization processes which allows for calculations not only correlation functions C 2 ( Q inv ) (one-dimensional) but also corresponding to them C 2 ( Q x,y,z ) (i.e., three-dimensional). The method is based on the bunching of identical bosonic particles in elementary emitting cells (EEC) in phase space in manner leading to proper Bose-Einstein form of distribution of energy (this was enough to calculate C 2 ( Q inv )). To obtain also C 2 ( Q x,y,z ) one has to add to it also symmetrization of the multiparticle wave function to properly correlate space-time locations of produced particles with their energy-momentum characteristics.
