Heavy quark state production and suppression via Xe-Xe collisions at $\sqrt{s_{pp}}$=5.44 TeV

TL;DR

This paper estimates production and suppression rates of various heavy quarkonium states in Xe-Xe collisions at 5.44 TeV, using hybrid theory to account for mixed states, providing insights into quark-gluon plasma effects.

Contribution

It introduces a method to calculate differential rapidity cross sections for heavy quarkonium states in Xe-Xe collisions, incorporating hybrid meson states for the first time.

Findings

Predicted production cross sections for $J/ au$, $ au(2S)$, $(1S)$, $(2S)$, $(3S)$.

Estimated suppression ratios for excited states relative to ground states.

Demonstrated the impact of hybrid states on production and suppression patterns.

Abstract

We estimate differential rapidity cross sections for $J/\Psi$, $\Psi(2S)$, $\Upsilon(1S)$, $\Upsilon(2S)$, and $\Upsilon(3S)$ production; and $\Psi(2S)$ to $J/\Psi(1S)$, $\Upsilon(3S)$ to $\Upsilon(1S)$ suppression via Xe-Xe collisions at proton-proton energy $\equiv \sqrt{s_{pp}}$ =5.44 TeV. For the $\Psi(2S)$, $\Upsilon(3S)$ states we use the mixed heavy quark hybrid theory, with these states being approximately 50\% standard and 50\% hybrid charmonium, bottomonium meson states.
