Description
High pT particle suppression in heavy ion collisions appears to be one of the most exciting discoveries at RHIC. The suppression is explained by jet-quenching via partonic energy loss in a hot and dense matter created in such collisions. Nevertheless, theoretical models tuned to describe hadron suppression versus pT and centrality suffer from ambiguities in description of collision dynamics, parton energy loss and cold nuclear matter effects. The latter can be studied by looking at d+Au collisions since it can be safely assumed that no hot and dense medium is being created.
The PHENIX experiment at RHIC has performed light meson production measurements in d+Au collisions at sqrt(s_NN) = 200 GeV. This poster will deliver the latest results obtained from high statistics 2008 data sample for omega, phi, k-short and eta-prime mesons. We will present analyses approaches used to obtain particle yields in different hadronic and leptonic decay channels and its nuclear modification factors. The poster will also concentrate on systematic study of neutral meson production in d+Au collisions at sqrt(s_NN) = 200 GeV.
