$J/\Psi$, $\Psi(2S)$ Production in pp Collisions at E=510 GeV

TL;DR

This paper reports on the measurement of $J/ au$ and $ au(2S)$ production in proton-proton collisions at 510 GeV, extending previous studies at 200 GeV to higher energy to understand quarkonium production mechanisms.

Contribution

It provides new experimental data on quarkonium production at 510 GeV, expanding the energy range of previous measurements at 200 GeV.

Findings

Measured production cross sections at 510 GeV

Compared results with lower energy data

Enhanced understanding of quarkonium production mechanisms

Abstract

This brief report is an extension of studies of $J/\Psi,\Psi(2S)$ production in pp collisions at the BNL with E=$\sqrt{s}$=200 GeV to E=510 GeV at PHENIX.
