Strange-baryon production asymmetry in K ± N interactions

Abstract.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.

Charmed particle production in hadron-hadron collisions

In the framework of Quark-Gluon-String Model developed recently in ITEP we calculate spectra of charmed particlesD,Ds,Λc,Ξc,Ωc in hadron-hadron collisions taking into account the decays ofS-wave resonances like D*,Ds*,Σc,Σc*,Ξc*,Ξc′, and Ωc*. We describe the bulk of the existing data onD, D*, adΛc production in πp andpp collisions and predict the yield of charmed particlesin Σ−p and Ξ−p reactions at hyperon beam energies of 340 GeV/c and 600 GeV/c. Because of significant production of baryon resonances our predictions for unfavored fragmentation differ from predictions of other models which do not take resonance production into account.

Inelastic nuclear screening for different secondaries produced in p+Pb collisions at LHC energy

We calculate the inclusive spectra of secondaries produced in soft (minimum bias) p+Pb collisions in the framework of Quark-Gluon String Model at LHC energy, by taking into account the inelastic screening corrections (percolation effects). The role of these effects is expected to be very large at the very high energies, and they should decrease the spectra more than 2 times in the midrapidity region at sqrt(s)_(NN) = 5 TeV. The experimental data confirm such a picture, which means that the nuclear screening effects are connected with the Pomeron interaction rather than with the interactions of the produced secondary particles in the final state.

Hadroproduction of neutral Kstar-mesons up to LHC energies

-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.
