R. Raniwala et al., Determination of azimuthal anisotropy of neutral pions from the measured anisotropy of photons in ultra-relativistic nuclear collisions, PHYS LETT B, 489(1-2), 2000, pp. 9-14
A method is suggested to deduce the anisotropy in neutral pions by measurin
g the azimuthal anisotropy of photons in ultra-relativistic nuclear collisi
ons. 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 mul
tiplicity and anisotropy. This parameter can be determined from experimenta
l data. (C) 2000 Published by Elsevier Science B.V.
