CORRELATIONS AND INTERMITTENCY IN HIGH ENERGY MULTIHADRON DISTRIBUTIONS

Abstract
The linked-pair approximation to the hierarchy of cumulant correlation functions is tested in the central rapidity domain, where approximate translation invariance is appropriate. The bin-averaged factorial moments up to the fifth order are well described in terms of the second-order experimental moment for final states created in hadronic collisions. Given the two-particle correlation function, the only constants appearing in the higher moments are very close to those-appropriate to the negative binomial distribution, as pointed out recently by De Wolf. The close correspondence of the linked-pair decomposition to the same structure occurring in galaxy correlations (with slightly different coefficients) is noted, as is the apparently negative binomial character of the number distribution of galaxies in clusters. Preliminary results are discussed for the rapidity distributions arising in proton-nucleus and nucleus-nucleus collisions. We present a variety of fits to correlation functions and also discuss bin-bin correlations deriving from our model.
