Low Mass Vector Meson Measurements via Di-electrons at RHIC by the PHENIX Experiment

TL;DR

This paper reports measurements of omega and phi mesons in various collision systems at RHIC using di-electron decay channels, providing insights into their transverse momentum spectra across different conditions.

Contribution

It presents the first comprehensive comparison of omega and phi meson spectra in p+p, d+Au, and Au+Au collisions at RHIC through di-electron decay channels.

Findings

Transverse momentum spectra vary with collision system and centrality.

Consistent results between hadronic and di-electron decay channels.

Data contribute to understanding meson production and medium effects.

Abstract

The PHENIX experiment at RHIC has measured $\omega$ and $\phi$ mesons in $p+p$, $d+Au$ and $Au+Au$ collisions at \sqn = 200 GeV via both hadronic and di-electron decay channels. The transverse momentum spectra as measured in different decay modes and at different centralities are shown and discussed here.
