Description
The STAR Spin program aims to measure the gluon helicity distribution $\Delta g(x)$ in the proton, which remains highly unconstrained at small momentum fractions $x < 0.05$. Dijet reconstruction in polarized proton collisions at $\sqrt s = 500$ GeV will extend these constraints by sampling lower $x$ gluons while also providing more precise information about the partonic kinematics. This contribution will present studies of the anti-$k_T$ jet algorithm, the dijet selection procedure, and progress towards the first measurement of the dijet cross-section at $\sqrt{s}=500$ GeV from ~10 $pb^{-1}$ of data collected in 2009.
