Description
Multi-particle azimuthal correlations have recently been measured in proton/deuteron-nucleus collisions at RHIC and at the LHC, and call for theoretical explanations. In particular, whether they originate from the initial or final state interaction is a matter of intense debate. We propose a new, initial-state mechanism to generate multiple correlations like $c_2\{4 \}$ from the combined effect of multi-parton scattering and the elliptic gluon Wigner distribution of the nucleus. This can arise even if the individual parton-nucleus scatterings are independent of each other. We present a numerical estimate of this effect by using the Wigner distribution computed from the impact parameter dependent Balistky-Kovchegov equation.
