Dynamical and Bose-Einstein correlations of centrally produced pion pairs in hadron-hadron collisions

Abstract

We calculate dynamical and Bose-Einstein inclusive correlations of pion pairs (as functions of the invariant pair mass M ππ ) from the decay of independently produced clusters, whose finite size is explicitly taken into account. We show that recent pp bubble chamber data from FNAL on the correlation functions C 2( M ππ ) for centrally produced π + π − and π − π − pairs can be understood within this picture. Some implications for Hanbury-Brown-Twiss type analyses are discussed.
