Abstract
Bose-Einstein correlations between like-sign pions have been investigated in e+e- annihilation at s =29 GeV using the Time Projection Chamber detector at the SLAC e+e- storage ring PEP. The production rate of like-sign pion pairs with small relative momentum is found to be increased by more than 50% over the rate expected for uncorrelated production of pions. From the correlation length, a typical source radius of 0.65 fm is derived. Data are consistent with a spherical shape of the pion source. No dependence of radius or correlation strength on the event multiplicity is observed.
