$\Psi$ and $\Upsilon$ production via $\sqrt{s_{pp}}$=8 TeV p-Pb collisions

TL;DR

This paper estimates differential rapidity cross sections for $ ext{ extPsi}$ and $ ext{ extUpsilon}$ production in 8 TeV p-Pb collisions using a hybrid theory that includes both standard and hybrid meson states.

Contribution

It extends previous heavy-quark production models by incorporating mixed hybrid states for certain mesons in p-Pb collisions at 8 TeV.

Findings

Differential rapidity cross sections calculated for $ ext{ extPsi}$ and $ ext{ extUpsilon}$ states.

Hybrid theory predicts approximately 50% hybrid composition for $ ext{ extPsi}(2S)$ and $ ext{ extUpsilon}(3S)$.

Extension of hybrid meson production models from A-A collisions to p-Pb collisions.

Abstract

We estimate differential rapidity cross sections for $\Psi$ and $\Upsilon$ production via p-Pb collisions at 8 TeV. We use the mixed heavy quark hybrid theory in which the $J/\Psi(1S),\Upsilon(1S),\Upsilon(2S)$ are standard mesons while the $\Psi(2S)$ and $\Upsilon(3S)$ are mixed hybrids, approximately 50% standard $|q \bar{q}>$ states and 50% hybrid $|q \bar{q} g>$ states. This is an extension of previous work on heavy-quark state production via A-A collisions at RHIC.
