The dependence of transverse momentum spectra of neutral pions and η mesons with pT < 16 GeV/c and pT < 12 GeV/c, respectively, on the centrality of the collision has been measured at midrapidity by the PHENIX experiment at the BNL Relativistic Heavy Ion Collider (RHIC) in d + Au collisions at √sNN = 200 GeV. The measured yields are compared to those in p + p collisions at the same √sNN scaled by the number of underlying nucleon-nucleon collisions in d + Au. At all centralities, the yield ratios show no suppression, in contrast to the strong suppression seen for central Au + Au collisions at RHIC. Only a weak pT and centrality dependence can be observed.
