Query: PHENIX measurement of high p_T particles in Au+Au and d+Au collisions at
  sqrt{s_{NN}} = 200 GeV   We present new results on the production of charged hadrons and neutral pions
in Au+Au and d+Au collisions at sqrt{s_{NN} = 200 GeV, measured within the
PHENIX experiment. We observe the opposite centrality dependence when comparing
the two collision systems: an increase with centrality compared to the binary
scaled yield from p+p collisions in d+Au and a decrease with centrality in
Au+Au.
