In Run-7 of RHIC operations PHENIX has recorded over 5.4 billion minimum bias events, facilitating a detailed study of deuteron and antideuteron production as a function of centrality and up to transverse momentum of p T =5 GeV/c. We present transverse momentum p T and transverse mass m T spectra, mean transverse momentum 〈p T 〉, source parameters, particle ratios, and nuclear modification factor R CP . Deuteron and antideuteron spectra are compared to those of other identified particles and to hydrodynamical predictions.
