We discuss the angular correlation present in hadron–hadron collisions at large rapidity difference (
). 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 (
) decrease substantially as a function of 
, while the even harmonics (
) increase considerably with the growth of .
