Jet properties from $π^{\pm}$ - $h^{\pm}$ correlation in $p+p$ and $d$+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV

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 $π^{\pm}-h^{\pm}$ correlation function in $Δϕ$ and $Δη$. 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.
