摘要：

We present the first measurements of the longitudinal double-spin asymmetry A(LL) for dijets with at least one jet reconstructed within the pseudorapidity range 0.8 < eta < 1.8. The dijets were measured in polarized pp collisions at a center-of-mass energy root s = 200 GeV. Values for A(LL) are determined for several distinct event topologies, defined by the jet pseudorapidities, and span a range of parton momentum fraction x down to x similar to 0.01. The measured asymmetries are found to he consistent with the predictions of global analyses that incorporate the results of previous RHIC measurements. They will provide new constraints on Delta g(x) in this poorly constrained region when included in future global analyses.
