In these proceedings we present STAR measurements of two-particle azimuthal correlations between trigger particles at mid-rapidity (|η| < 1) and associated particles at forward-rapidities (2.7 <|η|< 3.9) in p+p, d+Au and Au+Au collisions at . Two-particle azimuthal correlations between a mid-rapidity trigger particle and forward-rapidity-associated particles preferably probe large-x quarks scattered off small-x gluons in RHIC collisions. Comparison of the separate d- and Au-side measurements in d+Au collisions may potentially probe gluon saturation and the presence of colour glass condensate. In Au+Au collisions quark energy loss can be probed at large rapidities, which may be different from gluon energy loss measured at mid-rapidity.
