Contribution

It provides an analysis of the possible effects of missing resonances on heavy-ion collision studies and explores their quantum number characteristics.

Findings

Missing resonances could significantly influence heavy-ion collision outcomes

Predicted states may have specific quantum numbers affecting experimental detection

Understanding these states is crucial for accurate QCD modeling

Abstract

Between 2004 until today many new resonances in the QCD spectrum have been added by the Particle Data Group. However, it is still possible that there are further states that have yet to be measured, as predicted by Lattice QCD calculations and Quark Models. In this paper I review how these missing states would influence the field of heavy-ion collisions. Additionally, the quantum numbers that characterize these missing states are also discussed.
