Abstract:

The structure of the event as described by some average variables, like the mean charged multiplicity and the mean multiplicity of the V0 (K0 + Lambda) as well as the strength of the intermittency like correlation, is analysed as a function of the average event Pt. Multibody final state from minimum bias and jet trigger events are examined for the two available center of mass energies 1800 and 630 GeV.
