Strange baryon production asymmetry in K(+-)N interactions
The asymmetry of strange baryon production in Kp interactions at high
energies is considered in the framework of the Quark-Gluon String Model. The
contribution of the String-Junction Mechanism to the strange baryon production
is analysed.Comment: Contribution to the proceedings of the IV International Conference on

Midrapidity hyperon production in pp and pA collisions from low to LHC energies
The experimental data on p, Lambda, Xi-, Omega-, 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.Comment: 23 pages, 12 figures, and 3 tables. arXiv admin note: substantial

Hadroproduction of neutral Kstar-mesons up to LHC energies
We consider the experimental data on neutral Kstar-meson production on
nucleon and nuclear targets. The Quark-Gluon String Model quantitatively
describes the inclusive density in the midrapidity region, as well as the
initial energy and A dependences of the produced Kstar-mesons.Comment: 19 pages, 8 figures, and 4 tables. arXiv admin note: text overlap

Baryon Number Transfer in Hadronic Interaction
The process of baryon number transfer due to string junction propagation in
rapidity is considered. It has a significant effect in the net baryon
production in collisions at mid-rapidities and an even larger effect in
the forward hemisphere in the cases of and interactions. The
results of numerical calculations in the framework of the Quark-Gluon String
model are in reasonable agreement with the data.Comment: Latex, 17 figs. in ps files, 1 table. Submitted to EPJ C The title of
