Description
Dileptons and photons, emitted throughout the evolution of the hot and dense QCD medium in relativistic heavy-ion collisions, serve as an effective probe due to their minimal strong interactions. Precise measurements of the dilepton mass continuum and the direct photon transverse momentum spectrum uniquely enable the extraction of critical medium properties, notably the temperature at various evolution stages. Additionally, since the thermal emission rates are proportional to the medium’s electromagnetic spectral function, integrated dilepton and photon yields provide valuable insights into the microscopic interaction mechanisms between the electromagnetic current and the QCD medium. In this talk, I will present a concise overview of the EM probes, highlight recent key experimental results, and discuss prospects for future investigations.
