Non-identical particle correlations at 62 and 200 GeV at STAR

We report on STAR analyses of p−Λ, , , , and π−Ξ correlations in Au+Au collisions at and 200 GeV. Measured source sizes in and are shown to be in qualitative agreement with flow expectations. Interaction potential between , was investigated by measuring scattering length, thus showing that correlation analyses in heavy-ion collisions can be used to study strong interaction potential between hadrons. We present also analyses of π−Ξ correlations addressing independently on previous measurements the issue of Ξ flow in heavy-ion collisions.
