Bose-Einstein correlations in e+e- annihilation in the γ(1S) and continuum
Bose-Einstein correlations in direct γ(1S) decays and continuum in the energy region √s=7.2-10.3 GeV have been studied using data taken with the MD-1 detector at VEPP-4 storage ring. Assuming gaussian density of the pion source the data indicate the radius of the source π=0.73±0.10±0.04 fm for direct γ (1S) decays and π=0.83±0.22±0.05 fm for the continuum. The correlation strengths λ for both data samples also are similar. Thus Bose-Einstein correlations do not reveal a noticeable difference between quark and gluon fragmentation. © 1996 Springer-Verlag.
