originates from the thermalization of charm quarks in the deconfined medium but suggests that additional mechanisms might be missing in the models.

Direct photon elliptic flow in Pb–Pb collisions √sNN = 2.76 TeV
ALICE Collaboration (Elsevier B.V., 2019)The elliptic flow of inclusive and direct photons was measured at mid-rapidity in two centrality classes 0–20% and 20–40% in Pb–Pb collisions at √sNN = 2.76 TeV by ALICE. Photons were detected with the highly segmented ... -
