Query: 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.
