Production of phi Mesons on Nuclear Targets in the Quark-Gluon String Model

摘要

Experimental data on the production of phi mesons in proton-nucleus and nucleus-nucleus collisions are considered. These data show unusually small shadowing corrections to the inclusive density for phi-meson production in the midrapidity region. It is found that the results of calculations based on the quark-gluon string model are in qualitative agreement with experimental data on the density of produced phi mesons as a function of both the initial energy ranging from the Collaboration NA49 energy to the LHC high energies and the target atomic number A.
