Description
Thermal dileptons, emitted throughout the space-time evolution of the hot QCD medium in relativistic heavy-ion collisions, interact weakly with surrounding partonic and hadronic matter. This minimal interaction makes them as idea penetrating probes, providing direct insights into the medium’s properties. Their invariant mass spectra, unaffected by blue-shift effects from the medium’s rapid collective expansion, offer a direct measure of the emitting source’s temperature. Furthermore, dileptons produced at distinct evolutionary stages dominate specific mass regions, enabling differential access to the medium’s temperature evolution. In this talk, we will review recent advancements in measuring thermal dilepton production and discuss their implications for understanding the thermodynamic properties of the quark-gluon plasma in heavy-ion collisions.
