Double Spin Asymmetries, $A_{LL}$, for Di-hadrons in PHENIX

The Relativistic Heavy Ion Collider (RHIC), through its polarized proton-proton collisions, provides leading order access to $\Delta$G, the gluon contribution to the proton spin. Previous measurements have shown $\int\Delta G(x) dx$ to be consistent with zero in the Bjorken-x range of 0.05 to 0.2, whereas there is presently no measurement constraining $\Delta$G (x) for x below or above this range. The Muon Piston Calorimeter provides the opportunity to expand the constrained range by allowing measurements of double spin asymmetries for azimuthally-separated pairs of $\pi^{0}'s$ at forward rapidity, $3.1<=|\eta|<=3.9$, for $\sqrt{s}$=200 GeV and 500 GeV data taken in 2009. We present PYTHIA simulations studying the kinematics and possible asymmetries from di-hadron production at RHIC.
