Experimental overview of electromagnetic probes in ultra-relativistic nucleus-nucleus collisions
arXiv:2212.01220
Abstract
Electromagnetic probes are not affected by hadronization and provide direct information about the space-time evolution of high-energy nucleus-nucleus collisions. In particular, the measurement of thermal radiation from the quark-gluon plasma and the extraction of an effective medium temperature belong to the key objectives in heavy-ion physics. We provide a brief tour of current results and an outlook to future measurements.
