BOSE-EINSTEIN CONDENSATION AND INDEPENDENT PRODUCTION OF PIONS

The influence of the HBT effect on the momentum spectra of independent ly produced pions is studied using the method developed earlier for di scussion of multiplicity distributions. It is shown that in this case all the spectra and multiparticle correlation functions are expressibl e in terms of one function of two momenta. It is also shown that at th e critical point all pions are attracted into one quantum state and th us form a Bose-Einstein condensate. (C) 1998 Elsevier Science B.V. All rights reserved.
