  We review recent results on the charged pion - charged hadron correlation in
$p+p$ and $d$ + Au collisions as measured by the PHENIX Collaboration.
Properties of di-jet system, such as the jet shape, associated hadron yield per
trigger pion, and the underlying event are extracted statistically from the
$\pi^{\pm}-h^{\pm}$ correlation function in $\Delta\phi$ and $\Delta\eta$. For
jet triggered with high $p_T$ pions ($p_T>5$ GeV/c), no apparent differences in
the jet properties are seen between $p+p$ and $d$ + Au.
