High $p_T$ resonances as a possibility to explore hot and dense nuclear matter

TL;DR

This paper explores how high transverse momentum resonances can be used to probe the properties of hot, dense nuclear matter created in ultrarelativistic heavy ion collisions, focusing on reconstructability across different densities.

Contribution

It analyzes the potential of baryonic and mesonic resonances at various densities to provide insights into the state of nuclear matter at high temperature and density.

Findings

Reconstructable resonance percentage varies with density.

Analysis covers energy range from 30 AGeV to 200 AGeV.

Potential to distinguish different phases of nuclear matter.

Abstract

One of the fundamental objectives of experiments with ultrarelativistic heavy ions is to explore strongly interacting matter at high density and high temperature. In this investigation we study in particular the information which can be obtained by analyzing baryonic and mesonic resonances. The decay products of these resonances carry information on the resonances properties at the space time point of their decay. We especially investigate the percentage of reconstructable resonances as a function of density for heavy ion collisions in the energy range between $E_{lab}$ = 30 AGeV and $\sqrt{s}$ = 200 AGeV, the energy domain between the future FAIR facility and the present RHIC collider.
