Thermal radiation and direct photon production measurements with dielectrons in Pb–Pb and pp collisions
The latest ALICE results on dielectron measurements in Pb–Pb collisions at √SNN = 5.02sNN=5.02 TeV, and in minimum-bias (MB) and high-multiplicity (HM) pp collisions at √S = 13s=13 TeV with LHC Run 2 data are reported. The results are compared to the predictions of dielectron yields from known hadro...

| description | The latest ALICE results on dielectron measurements in Pb–Pb collisions at √SNN = 5.02sNN=5.02 TeV, and in minimum-bias (MB) and high-multiplicity (HM) pp collisions at √S = 13s=13 TeV with LHC Run 2 data are reported. The results are compared to the predictions of dielectron yields from known hadronic sources and thermal radiation from the medium. The contribution of virtual direct photons is extracted from the data by fitting the measured invariant mass distributions. We present the direct to inclusive photon ratio, as well as the direct photon yield in both pp and central Pb–Pb collisions. |
