Two particle transverse momentum correlations have been investigated for proton-proton and deuteron-deuteron interactions at center-of-mass energy of NN collisions of 10 GeV. The correlations between Λ-hyperons and К-, π- mesons and protons are calculated in Geant4 FTF and Pythia 6.4 models. It is shown that PT-correlations between Λ-hyperons and strange particles are stronger in the FTF model than in Pythia one. The two particle PT-correlations can be studied at NICA SPD experiment. A study of the two particle correlations can help to clarify the mechanism of quark-gluon string fragmentation.
