Abstract
Two particle correlations between identified meson and baryon trigger particles with and lower charged hadrons have been measured at midrapidity by the PHENIX experiment at RHIC in , and collisions at . In noncentral collisions, the probability of finding a hadron near in azimuthal angle to the trigger particles is almost identical for mesons and baryons and significantly higher than in collisions. The associated yields for trigger baryons decrease in the most central collisions, consistent with some baryon production by thermal recombination in addition to hard scattering.
