Abstract
In this proceedings we present STAR measurements of two particle azimuthal correlations between trigger particles at mid-rapidity ( 1) and associated particles at forward rapidities (2.7 3.9) in p+p, d+Au and Au+Au collisions at = 200 GeV. 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 Color 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.
