Inclusive spectra of secondaries produced on nuclear targets at superhigh energies and with violation of Feynman scaling

Effects of Feynman scaling violation in yields of hadron secondaries inpA and πA collisions that arise when initial energy is increased are considered. There result from the growth of hadron-nucleon cross sections and an expected increase of the average transverse momenta of secondaries. The model of quark-gluon strings is used to calculate the inclusive spectra of secondaries. Interactions with a fixed number of nucleons are calculated, taking account of the growth of the slope parameter in elastichN scattering. Violation of Feynman scaling at superhigh energies turns out to be stronger than the additive quark model predicts it to be.
