String Fusion Mechanism and Studies of Correlations

The paper presents results on multiplicity correlations in two rapidity intervals and mean transverse momentum vs event multiplicity correlation function calculated in the developed Monte-Carlo model of multi-particle production run for p + p interactions at √(s_NN) = 900 and 7000 GeV. The model is based on interacting colour strings approach with longitudinal and transverse strings dynamics. Results are compared with the ALICE data and PYTHIA 8.3 simulations.
