Heavy Quark State Production via p-p and O-O Collisions

TL;DR

This paper analyzes the production rates of various heavy quarkonium states in proton-proton and oxygen-oxygen collisions at high energies, focusing on differential rapidity cross sections within a specific rapidity range.

Contribution

It provides new calculations of differential rapidity cross sections for multiple heavy quarkonium states in p-p and O-O collisions at 5.44 TeV, considering both normal and hybrid mesons.

Findings

Differential rapidity cross sections are computed for specified quarkonium states.

Hybrid and normal meson states are distinguished in the analysis.

Results are relevant for understanding quarkonium production in high-energy nuclear collisions.

Abstract

Here we have considered $J/\Psi$ is a normal charmonium meson, while $\Psi(2S)$ is a mixed hybrid charmonium meson. Similarly $\Upsilon(1S)$ and$\Upsilon(2S)$ are normal upsilon mesons, while $\Upsilon(3S)$ is a mixed hybrid upsilon meson. We discuss the differential rapidity cross sections for $J/\Psi$, $\Psi(2S)$, $\Upsilon(1S)$, $\Upsilon(2S)$, $\Upsilon(3S)$ production via p-p, and O-O collisions at proton-proton energy $\equiv \sqrt{s_{pp}}$= 5.44 TeV. The rapidity taken for the present study goes from y=-1 to 1.
