Forward Lambda_b production in p-p collisions at LHC

We present the theoretical results on the forward Lambda_b production in p-p collisions at LHC energies. It can give us useful information on the Regge trajectories of the bottom mesons.Comment: 4 pages, 3 figures.

Hadron production in

The self-consistent approach based on similarity of inclusive spectra of hadrons produced in pp and AA collisions is reviewed. We present its modification due to the quark-gluon dynamics to describe the inclusive spectra of hadrons produced in pp collision as a function of the transverse momentum pt at mid-rapidity. The extension of this approach to analyze the pion pt-spectra produced in AA collision at high and middle energies and mid-rapidity is given. A satisfactory description of experimental data on these spectra in pp and AA collisions within the offered approach is shown

Hadron production in pp and AA collisions at mid-rapidity within self-similarity approach

We present its modification due to the quark-gluon dynamics to describe the inclusive spectra of hadrons produced in pp collision as a function of the transverse momentum pt at mid-rapidity.

Analytical description of hadron production in hadron-hadron and nuclear-nuclear collisions in the mid-rapidity region

It is shown that the inclusive spectra of the produced hadrons in hadron-hadron and nuclear-nuclear collisions can be presented as the universal function dependent of the self-similarity parameter in the analytical form. The article gives a description of the self-similarity parameter depending on the rapidity in the mid-rapidity region. The experimental data are in good agreement with the results of our calculations in a wide energy range from a few GeV to a few TeV in the central rapidity region

Open charm production in binary reactions within the Regge theory

We analyze the open charm production in the binary $\pi p \to \bar{D} \Lambda_c$ and $\pi(\rho) J/\psi$ reactions within the Regge theory including the absorption corrections. The calculations show that the total cross section is about a few $\mu$b for the first processes and a few mb for the second reactions at energy close to the threshold. Then it decreases with increasing energy according to the true Regge asymptotics

Development of the Baldin approach for the relativistic nuclear interactions

This article presents the development of the A.M.Baldin approach using a description of relativistic nuclear interactions in the four velocity space. The modification of this approach taking into account the energy dependence of inclusive spectra of hadron has allowed us to describe the differential cross section as a function of the transverse momentum and a satisfactory description of the slopes of the hadron spectra as functions of the energy, has been obtained. The hadron spectra as functions of the energy, has been obtained. Results of our calculations have coincided with experimental data in a wide energy range with high precision
