The experimental investigations of the charged particles forward-backward multiplicity correlations and especially of the correlations in the transverse momenta can give us the information on the number of emitting centers and hence on the fusion of colour strings. It's significant that even low p_T-distributions in the central region contain this valuable information on the colour string fusion. The first results on the computations of forward-backward charged particles correlations on the basis of MC simulations using HIJING event generator for Pb-Pb collisions at LHC energies are presented. The results on multiplicity and p_T correlations are obtained at different values of the impact parameter and for different choices of forward-backward rapidity windows taking into account ALICE acceptance. In future we plan to study forward-backward correlations using another event generator based on DPM and QGSM, which enables the MC simulations with and without the string fusion. It enables to choose most adequate correlation variables for the registration of the possible string fusion in ALICE.
