Inplication of percolation of colour strings on multiplicities, correlations and the transverse momentum

In the colour string model the impact of string percolation on multiplicities, their long-range correlations and average transverse momentum is studied. The multiplicities are shown to be damped by a simple factor which follows from the percolation theory. A clear signature of the phase transition is found to be a behaviour of the correlations for intensive observables, such as average transverse momentum, which can be detected in the high-energy heavy ion collisions.
