Central and peripheral hadron-nucleus collisions in the Additive Quark Model

TL;DR

This paper models central and peripheral hadron-nucleus collisions using the Additive Quark Model, predicting interaction numbers that align with experimental data at LHC energies.

Contribution

It provides a detailed calculation of quark-nucleus interactions in different collision centralities within the Additive Quark Model, matching experimental results.

Findings

Average quark-nucleus interactions match experimental data.

Peripheral collisions involve interactions with one quark, central with all three.

Model accurately predicts particle production at LHC energies.

Abstract

Peripheral nucleon-nucleus collisions occur at the high energies mainly through the interaction with one constituent quark from the incident nucleon. The central collisions should involve all three constituent quarks and each of them can interact several times. We calculate the average number of quark-nucleus interactions for both the cases in good agreement with the experimental data on $\phi$-meson, $K^{*0}$ and all charged secondaries productions in $p+Pb$ collisions at LHC energy $\sqrt s = 5$ TeV.
