Abstract

We report on STAR analyses of p-lambda, p_bar-lambda_bar, p-lambda_bar, p_bar-lambda, p-p_bar and pi-Xi correlations in Au+Au collisions at sqrt(S_NN)=62 and 200 GeV. Measured source sizes in p(p_bar)-lambda(lambda_bar) and p-p_bar are shown to be in qualitative agreement with flow expectations. Interaction potential between p-lambda_bar, p_bar-lambda 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 pi-Xi correlations addressing independently on previous measurements the issue of Xi flow in heavy-ion collisions.
