Sas, M. (2019). Direct photon elliptic flow in Pb–Pb collisions at sNN=2.76TeV. Nuclear Physics A, 982, 195-197. 10.1016/j.nuclphysa.2018.10.065Sammendrag
The elliptic flow of inclusive and direct photons was measured by ALICE for central and semi-central Pb–Pb collisions at √sNN = 2.76 TeV. The photons were reconstructed using the electromagnetic calorimeter PHOS and the central tracking system. The inclusive photon flow reconstructed with both methods are combined and used to extract the direct photon flow, using a decay photon simulation and the direct photon excess Rγ, in the transverse momentum range 0.9 < pT < 6.2 GeV/c. We find that the theoretical predictions generally under-predict the results.
