    Description
    - Calculation of Secondary Multiplicities in pp Collisions at LHC Energies by the Quark-Gluon String Model, by Carlos Merino 'We consider in detail the transfer of baryon number in rapidity space due to the string-junction propagation. The numerical predictions for midrapidity inclusive densities of different secondaries in the framework of the Quark-Gluon String Model for pp collisions at LHC energies are presented. Finally, the crucial importance of high accuracy measurements of the baryon/antibaryon ratios at sqrt(s) = 14.TeV is stressed'. - Studies of the baryon number transport at LHC energies with the ALICE experiment by Panos Christakoglou 'Ratios of particle production in hadronic interactions are important indicators of the collision dynamics. In particular, the detailed analysis of the /p and /Λ ratios are of great importance since they allow to determine the carrier of the baryon number (BN). The Large Hadron Collider (LHC) will provide p+p collisions up to a center-of-mass energy of √s = 14TeV and Pb+Pb collisions up to √sNN = 5.5TeV. The ALICE experiment, due to its particle identification capabilities, will allow us to study several baryon species (p, Λ, Ξ, Ω and their antiparticles) at mid-rapidity (|y| < 1.0) with a wide transverse momentum coverage (0.3 ≤ pT ≤ 5GeV/c) and high precision. Since the two dominant transport mechanisms for the BN produce only small differences in the observed baryon ratios, it is mandatory to understand in great detail the sources of the systematical uncertainties of these measurements. In this presentation, the expected performance of the ALICE detector setup regarding the rapidity, transverse momentum and energy dependence of the /p and /Λ will be discussed and the limits for the systematical uncertainties of these measurements will be given'.
