Abstract

We discuss the angular correlation present in hadron–hadron collisions at large rapidity difference (α¯Sy12≫1). We find that in the CGC/saturation approach the largest contribution stems from the density variation mechanism. Our principal results are that the odd Fourier harmonics (v₂ _n ₊ ₁) decrease substantially as a function of y₁₂, while the even harmonics (v₂ _n) increase considerably with the growth of y₁₂.
