Jet structure of baryon excess in Au+Au collisions at root SNN=200 GeV

Summary, in English

Two particle correlations between identified meson and baryon trigger particles with 2.5<p(T)(T)(<4.0 GeV/c and lower p) (charged hadrons have been measured at midrapidity by the PHENIX experiment at RHIC in p+p,d+Au, and Au+Au collisions at s)(NN) = 200 GeV. In noncentral Au+Au 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 p+p 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.
