Abstract
Experimental data obtained by the NA35 Collaboration for the difference of the p and \(\bar p\) spectra and the difference of the Λ and \(\bar \Lambda\) spectra (net proton and Λ-hyperon spectra), as well as the inclusive Λ and \(\bar \Lambda\) spectra measured by the NA49, NA57, and STAR Collaborations, are compared with the predictions of the quark-gluon string model. The contribution of string-junction diffusion is calculated, and interaction with nuclear clusters is taken into account along with the corrections for inelastic screening. The level of numerical agreement with experimental data is between 20 and 30%. The predictions for the LHC energy are given.
