摘要:
From the study of even and odd multiplicity distributions for hadron-hadron collision in different rapidity windows, we propose a simple picture for charge correlation with nonzero correlation length and calculate the multiplicity distributions and the normalized moments in different rapidity windows at different energies. The results explain the experimentally observed coincidence and separation of even and odd distributions and also the anomalous energy dependence of normalized moments in narrow rapidity windows. The reason for the separation of even-odd distributions, appearing first at large multiplicities, is shown to be energy conservation. The special role of no-particle events in narrow rapidity windows is pointed out.

摘要:
The relation between multiplicity and transverse energy in high energy h-h and A-A collisions is investigated using a Monte Carlo generator of nondiffractive processes. The width of multiplicity fluctuation D/<n> for fixed E⊥ is found to be small and approximately constant for a wide range of E⊥.
