Abstract

The experimental data on p , , , -baryons and the corresponding antibaryons spectra obtained by different collaborations are compared with the results of the calculations performed into the frame of the quark-gluon string model. The contribution of string junction diffusion and the inelastic screening corrections are accounted for in the theoretical calculations. The predictions of the quark-gluon string model both for pp and pA collisions are extended up to the LHC energies.
