Soft processes in pp and AA interactions are considered in the framework of phenomenological
model with color strings formation and fusion. Elementary parton collisions are realized in the
model as the interaction of two colour dipoles from projectile and target nucleons. Modeling of
the exclusive distributions of parton momentum fractions and transverse coordinates is performed.
The interaction of colour strings in transverse plane is carried out in the framework of local string
fusion model with the introduction of the lattice in the impact parameter plane and taking into
account the finite rapidity length of strings. The parameters were fixed with experimental data on
pp total inelastic cross section and charged multiplicity.
The model was used for the calculation of long-range correlations between the multiplicities (n)
and the mean transverse momenta (pt) of charged particles. The dependence of n-n, pt-n, pt-pt
correlations on the width and position of the backward and forward rapidity windows was studie
