$\pi^0-\pi^0$ Azimuthal Correlations Comparisons Between PYTHIA and 2008 PHENIX Data

The Muon Piston Calorimeter Extension (MPC-Ex) is housed in front of the Muon Piston Calorimeter (MPC), a sub-detector of PHENIX at RHIC. Using the forward rapidity ($3<\eta<3.8$) arm of the MPC-Ex we can measure the low-$x$ portion of the nuclear wave function and the energy loss in cold nuclear matter using the 2016 $d$+Au run. However, there is no $p$+$p$ baseline for the 2016 $d$+Au run. Using PYTHIA we can create a baseline to compare the 2016 run data. In order to assure the validity of the PYTHIA, we compare the simulation to 2008 $p$+$p$ and $d$+Au $\pi0$-$\pi0$ correlations measured by PHENIX.
