Description

PHENIX measured two-particle angular correlations between high $p_T$ ($2 < p_T < 11 $ GeV/c) $\pi^{0}$ at midrapidity $|\eta| < 0.3 $ and hadrons emitted at
forward $(3.1<\eta<3.9)$ or backward $(-3.7<\eta<-3.1)$ rapidity in 200 GeV
p+p and d+Au collisions at $\sqrt{s_{NN}}$=200 GeV. In the Au-going direction the azimuthal correlations of these particle pairs with this large rapidity gap exhibit a ridge-like structure. This structure persists up to $p_{T} \approx 6$ GeV/c and strongly depends on collision centrality. It is reminiscent of collective behavior in A+A collisions. The ridge-like structure is absent in the d-going direction as well as in p+p collisions.

We present the final results of two particle correlations with a large rapidity
gap in 200 GeV d+Au and p+p collisions and discuss the physics implication of
the results.
