Abstract
We present the first measurements of the longitudinal double-spin asymmetry for dijets with at least one jet reconstructed within the pseudorapidity range . The dijets were measured in polarized collisions at a center-of-mass energy . Values for are determined for several distinct event topologies, defined by the jet pseudorapidities, and span a range of parton momentum fraction down to . The measured asymmetries are found to be consistent with the predictions of global analyses that incorporate the results of previous RHIC measurements. They will provide new constraints on in this poorly constrained region when included in future global analyses.
