Experimental aspects of quarkonia production and suppression in cold and hot nuclear matter

TL;DR

This paper reviews experimental observations of how quarkonia production is altered in nuclear collisions due to hot and cold nuclear matter effects, highlighting the physical mechanisms involved.

Contribution

It provides a comprehensive overview of experimental results related to quarkonia suppression and modification in both hot and cold nuclear matter environments.

Findings

Quarkonia production is suppressed in hot nuclear matter due to energy density effects.

Cold nuclear matter effects influence quarkonia formation in nuclear targets.

Experimental data helps distinguish between hot and cold matter effects on quarkonia.

Abstract

When heavy Quarkonia are formed in collisions between between nuclei, their production cross section is modified relative to that in p+p collisions. The physical effects that cause this modification fall into two categories. Hot matter effects are due to the large energy density generated in the nuclear collision, which disrupts the formation of the quarkonium state. Cold nuclear matter effects are due to the fact that the quarkonium state is created in a nuclear target. I will review experimental aspects of quarkonia production due to both hot and cold matter effects.
