Elliptic flow of thermal photons and formation time of quark gluon plasma at RHIC


We calculate the elliptic flow of thermal photons from Au+Au collisions at RHIC energies for a range of values for the formation time Ο„0\tau_0 but fixed entropy (or particle rapidity density). The results are found to be quite sensitive to Ο„0\tau_0. The v2v_2 for photons decreases as Ο„0\tau_0 decreases and admits a larger contribution from the QGP phase which has a smaller v2v_2. The elliptic flow coefficient for hadrons, on the other hand, is only marginally dependent on Ο„0\tau_0.Comment: 2 extra figures and discussion added.
