Dilepton radiation measured in PHENIX probing the strongly interacting matter created at RHIC

TL;DR

This paper reports measurements of electron-positron pairs in proton-proton and gold-gold collisions at RHIC, providing insights into the properties of the dense, strongly interacting matter created in these high-energy nuclear collisions.

Contribution

It presents new measurements of dilepton radiation in heavy-ion collisions, linking experimental data to the properties of the quark-gluon plasma.

Findings

Electron pairs observed vary with mass and transverse momentum.

Data can be used to probe the dense matter properties.

Relation between electron pairs and virtual photons discussed.

Abstract

PHENIX has measured $e^+e^-$ pairs from p+p and Au+Au collisions as function of mass and $p_T$. The data can be used to probe the properties of dense matter formed in Au+Au collision. The relation between electron pairs and virtual photons is discussed.
