> Abstract:
> 
> The dependence of transverse momentum spectra of neutral pions and eta
> mesons with pT <16 GeV/c and pT < 12 GeV/c, respectively, on the centrality
> of the collision has been measured at mid-rapidity by the PHENIX experiment
> at RHIC in d+Au collisions at sqrt{s_{NN}} = 200 GeV. The measured yields
> are compared to those in p + p collisions at the same sqrt{s_{NN}} 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.
