dc.description.abstract | Recent experimental results have revealed a surprisingly rich structure of multiparticle azimuthal
correlations in high energy proton–nucleus collisions. Final state collective effects can be responsible for
many of the observed effects, but it has recently been argued that a part of these correlations are present
already in the wavefunctions of the colliding particles. We evaluate the momentum space 2-particle
cumulant azimuthal anisotropy coefficients vn{2}, n = 2, 3, 4 from fundamental representation Wilson
line distributions describing the high energy nucleus. These would correspond to the flow coefficients
in very forward proton–nucleus scattering. We find significant differences between Wilson lines from
the MV model and from JIMWLK evolution. The magnitude and qualitative transverse momentum
dependence of the vn{2} values suggest that the fluctuations present in the initial fields are a significant
contribution to the observed anisotropies. | |
