Determination of Azimuthal Anisotropy of Neutral Pions from the Measured Anisotropy of Photons in Ultra-relativistic Nuclear Collisions

A method is suggested to deduce the anisotropy in neutral pions by measuring the azimuthal anisotropy of photons in ultra-relativistic nuclear collisions. The ratio of the estimated anisotropy in photons to the anisotropy in neutral pions is seen to scale with a parameter which depends on photon multiplicity and anisotropy. This parameter can be determined from experimental data.
