PHENIX has measured the transverse momentum (pT) spectra and two particle angular correlations for high pT particles in d +Au collisions at 
using the RHIC Year-2008 run data. The azimuthal angle correlations for two particles with a large rapidity gap exhibit a ridge-like structure. Using the π0s reconstructed in the EMCal, we have successfully extended the pT reach of the correlation up to 8GeV/c. We find that the azimuthal anisotropy of hadrons found at low pT persists up to 6GeV/c with a significant centrality and pT dependence, similar to what was observed in A+A collisions.
