Production of φ Mesons on Nuclear Targets in the Quark–Gluon String Model

Abstract

We consider the experimental data on ϕ-meson production on nuclear targets, and we find that they present unusually small shadow corrections for the inclusive density in the midrapidity region. We also give a quantitatively consistent description of both the initial energy dependence and the A-dependence of the produced ϕ-mesons, obtained in the frame of the Quark-Gluon String Model.PACS. 25.75.Dw Particle and resonance production 1 arXiv:1610.06039v1 [nucl-th]

Hadroproduction of neutral K*-mesons up to LHC energies

“…In the case of production of such a particles as pions and kaons, which give the main contribution to mean multiplicity at RHIC energies, the shadowing effects already appear at RHIC [18]. In the case of K * -meson production, as well as in the case of ϕ-meson production [4], the inelastic shadowing effects only appear at LHC energies. This behaviour can be connected with the relatively large mass of K * .…”

“…The hadroproduction of vector ϕ-mesons in the frame of Quark-Gluon String Model (QGSM) [1,2] was considered in [3,4].…”

“…The description of the production of secondary pseudoscalar mesons π and K, and of baryons p, p, Λ, and Λ, was obtained in [9,10,11,12]), while vector meson production was considered in [3,4,13,14].…”
