1305.3540 (Takao Sakaguchi et al.)

Cold nuclear matter effect measured with high pT hadrons and jets in
200GeV d+Au collisions in PHENIX

Takao Sakaguchi, for the PHENIX collaboration
High pT \pi^0 and \eta, as well as jets are measured using high statistics d+Au collision data collected in RHIC Year-2008 run. Both R_{dA} and R_{cp} for three observables are found to be very consistent each other within quoted systematic and statistical uncertainties. It was found that the R_{dA} is strongly centrality dependent as opposed to the expectations from theoretical models. An explanation of the centrality dependence from the experimental point of view is presented.
