Azimuthal anisotropy of direct photons in Au$+$Au collisions at $\sqrt{s_{{}_{NN}}}=200$ GeV

PHENIX Collaboration, N. J. Abdulameer, U. Acharya +322

The PHENIX experiment at the Relativistic Heavy Ion Collider measured the second Fourier component $v_2$ of the direct-photon azimuthal anisotropy at midrapidity in Au$+$Au collisi…
