Abstract

Over the past few years, the PHENIX detector has undergone several upgrades in the forward region (1<|η|≤4). Initially covered only by the muon arms, the addition of the MPC and the future FOCAL expands on the physics capabilities of the PHENIX detector. The focus of these upgrades is toward a better understanding of the Color-Glass Condensate (CGC) and the interplay between the different components of the proton's spin valence/sea quark and gluon contributions. These proceedings highlight the latest results from the MPC related to the CGC as well the newly proposed forward calorimeter detector, FOCAL. Both detectors aim to constrain the current view of gluon saturation at small x in the Color-Glass condensate framework, through correlations using π0's (MPC and FOCAL) and isolated direct photons (FOCAL) at high-pT over a broad range of pseudorapidity.
