Imprinting Quantum Fluctuations on Hydrodynamic Initial Conditions

Abstract

Starting from the two-point covariance function derived in [1], we have developed a toy model to investigate the effect of gluonic fluctuations on the transverse energy profile predicted by MC-KLN Color-Glass Condensate initial conditions. We find that the effect of these fluctuations on the eccentricity harmonics varies strongly with the correlation length and consequently the value of the fixed saturation momentum Qs used in [1]. Using approximate values for the minimum and maximum saturation momenta probed at RHIC in Au-Au collisions, we estimate the increase in the eccentricity coefficients resulting from gluonic fluctuations is as large as 10 to 20 percent in central collisions.
