PHENIX results on centrality dependence of yields and correlations in $d$+Au collisions at $\sqrt{s_{{}_{NN}}}$=200\,GeV

Abstract

PHENIX has measured the transverse momentum ($p_{\mathrm{T}}$) spectra and two particle angular correlations for high $p_{\mathrm{T}}$ particles in $d$+Au collisions at $\sqrt{s_{{}_{NN}}}$=200\,GeV 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 ${\pi }^0$ reconstructed in the EMCal, we have successfully extended the $p_{\mathrm{T}}$ reach of the correlation up to 8\,GeV/$c$. We find that the azimuthal anisotropy of hadrons found at low $p_{\mathrm{T}}$ persists up to 6\,GeV/$c$ with a significant centrality and $p_{\mathrm{T}}$ dependence, similar to what was observed in A+A collisions.
