N. Neumeister et al., THE INFLUENCE OF BOSE-EINSTEIN CORRELATIONS ON INTERMITTENCY IN P(P)OVER-BAR COLLISIONS AT ROOT-S=630 GEV, Zeitschrift fur Physik. C, Particles and fields, 60(4), 1993, pp. 633-642
The influence of Bose-Einstein correlations on the rise of factorial m
oments is small in the 1-dimensional phase space given by the pseudora
pidity eta, where the 2-body correlation function is dominated by unli
ke-sign particle correlations. Contrarily, the influence is dominant i
n the higher dimensional phase space. This is shown by using correlati
on integrals. They exhibit clear power law dependences on the four-mom
entum transfer Q2 for all orders investigated (i = 2-5). When searchin
g for the origin of this behaviour, we found that the Bose-Einstein ra
tio itself shows a steep rise for Q2 --> 0, compatible with a power la
