Measurement of $\pi^0$-hadron Azimuthal Correlations in $\sqrt{s_{_{NN}}}=200$ GeV $d$+Au Collisions with PHENIX

The Color Glass Condensate (CGC) explains both single particle and particle pair yield reductions at forward rapidity in $d$+Au collisions relative to $p$+$p$ collisions at the Relativistic Heavy Ion Collider (RHIC). The CGC also predicts the away-side width in two-particle azimuthal correlations will be broadened. In 2016, PHENIX collected $d$+Au data at $\sqrt{s_{_{NN}}}=200$ GeV. In this data, we can measure the $\pi^0$s in $|\eta|<0.35$ and $3<|\eta|<3.8$ and charge hadrons in $|\eta|<0.35$ and $1.4<|\eta|<2.2$. We measured $\pi^0$-hadron azimuthal correlations with different pair $\eta$ ranges. By varying the $p_T$ of the particles and the $\Delta\eta$ of the particle pairs, we can vary the $Q^2$ and $x$ of the target nucleus. The current status of the measurement will be shown.
