Pythia Study of Rapidity-Separated Two-Particle Correlations in $\sqrt{s}$=200 GeV $p$+$p$ collisions.

The PHENIX detector at the Relativistic Heavy Ion Collider collected data from $\sqrt{s_{_{NN}}}$ = 200 GeV $d$+Au collisions in 2016. This data set includes the MPC-EX which enhances $\pi^{0}$ identification at forward rapidity sensitive to low-$x$ partons in the Au nucleus. We are measuring $\pi^{0}$-hadron two particle azimuthal correlations in this data set for pairs separated in rapidity. We used PYTHIA to gain an intuition on how the away-side width is dependent on parton kinematics. In this poster, we will show the results of two-particle correlations in PYTHIA8. We find that the away-side width broadens with the rapidity gap. For triggers in the forward rapidity, the away-side width increases with $x$ of the target.
