Abstract:

The structure of the event as described by some average variables, like the mean charged multiplicity and the
mean multiplicity of the V$^{\circ}$ ($K^{\circ}_{s} + \Lambda^{\circ}$) as well as the strength of the
intermittency like correlation, is analysed as a function of the average event $p_{t}$. Multibody final state from
minimum bias and jet trigger events are examined for the two available center of mass energies 1800 and 630
GeV.
