Quarkonia measurement in p+p and d+Au collisions at by PHENIX Detector

We report new quarkonia measurements necessary to understand production mechanisms and cold nuclear matter effects in the yields observed at RHIC energy. Results obtained in p+p collisions collected during the 2006 RHIC Run include J/ψ, ψ′ and ϒ differential cross sections as well as J/ψ polarization. Revisited interpretations of the published J/ψ nuclear modification factors and statistically improved observations in d+Au collisions taken in the 2008 Run are also discussed in the view of the recent understanding of the initial state effects and breakup cross section.
