摘要
We analytically compute higher order cumulants of the azimuthal anisotropy, c(2){2m}, and corresponding v(2){2m} at high transverse momentum in the dilute-dense limit. The dense target is considered in the framework of the McLerran-Venugopolan model. The absolute values of the harmonics v(2){2m} of the azimuthal anisotropy are approximately equal, vertical bar v(2){2m}vertical bar approximate to vertical bar v2{2m'}vertical bar, for large m and m'. However, the harmonics with order 2m = 4n are complex. We argue that this is a generic property of connected graphs, which remains true in the dense-dense limit.
