Аннотация:It is shown that the quark-gluon string model gives a good description of the experimental multiplicity and rapidity distributions in collisions of pi+ and K+ mesons with Al and Au nuclei at 250 GeV/c. The version of the model with ''yo-yo'' time of hadron production is preferred. The MQ generator, which is used for calculations of spectra in hadron-hadron interactions at very high energies in cosmic rays, describesthe rapidity spectra of the secondary particles in the forward cone. A comparison is made for K+ Au collisions at 250 GeV/c and pAu collisions at 360 GeV/c. The experimental average transverse momentum of the particles in meson interactions with Al and Au nuclei are higher than the model predictions in both fragmentation regions.
