The process of baryon number transfer due to string junction propagation in rapidity space is considered. It leads to a significant effect in the net baryon production in pA collisions at mid-rapidities and an even more significant effect in the forward hemisphere for the cases of π A interactions. The results of numerical calculations in the framework of the Quark-Gluon String Model are in reasonable agreement with the data. Special consideration is given to Λ produced in π- A collisions extracted from the data of the WA89 Collaboration.

    We present the status of the description of hadron production in central nucleus-nucleus collisions within the statistical model. Extending previous studies by inclusion of very high-mass resonances (m > 2 GeV), and the up-to-now neglected scalar σ meson leads to an improved description of...

    In collisions of 40-GeV/c antiprotons with D, Li, C, S, Cu, and Pb nuclei, mean multiplicities of various secondary particles are investigated as functions of the mass number A. The mass-number dependence of the mean multiplicities of positively charged particles suggests that the effect of...

    Predictions were made for asymmetry between production spectra of Λ0 and $$\bar \Lambda ^0 $$ at the energy of LHC experiments. The value of A( s) should be situated in the corridor between two curves calculated in the quark-gluon string model with two possible values of intercept α SJ(0)...
