Description of phi-meson production in hadronic and nuclear collisions at very high energies

TL;DR

This paper reviews experimental and theoretical insights into phi-meson production in high-energy hadronic and nuclear collisions, demonstrating a successful description using the Quark-Gluon String Model across various energies and targets.

Contribution

It provides a comprehensive analysis of phi-meson production data and validates the Quark-Gluon String Model as an effective theoretical framework for these processes.

Findings

Good agreement between model and experimental data

Unusually small shadow corrections for nuclear targets

Consistent description across different collision energies

Abstract

We expose the current experimental and theoretical situation of the interesting case of the production of phi mesons in up to very high energy collisions of hadrons on both nucleon and nuclear targets, and we present a quantitavely good theoretical description of the corresponding experimental data, based on the formalism of the well established Quark-Gluon String Model, that has proved to be valid for a wide energy range. All the available experimental data for phi-meson production in hadron-nucleon collisions on the spectra of secondary phi, and on the ratios of phi/pi(-) and phi/K(-) production cross sections, as well the corresponding ones for phi-meson production on nuclear targets, are considered. In particular, it is seen that the production of phi-mesons on nuclear targets presents unusually small shadow corrections for the inclusive density in the central rapidity region.
