Glauber-based evaluations of the odd moments of the initial eccentricity relative to the even order participant planes

Abstract

Monte Carlo simulations are used to compute the centrality dependence of the odd moments of the initial eccentricity ${ϵ}_{n+1}$, relative to the even order (n) participant planes ${\Psi }_n^{\ast }$ in Au+Au collisions. The results obtained for two models of the eccentricity -- the Glauber and the factorized Kharzeev-Levin-Nardi (fKLN) models -- indicate magnitudes which are essentially zero. They suggest that a possible correlation between the orientations of the the odd and even participant planes (${\Psi }_{n+1}^{\ast }$ and ${\Psi }_n^{\ast }$ respectively), do not have a significant influence on the calculated eccentricities. An experimental verification test for correlations between the orientations of the the odd and even participant planes is also proposed.
