STAR has performed a correlation analyses of pion-kaon and pion-proton pairsfor sqrt(s_NN)=130 AGeV and sqrt(s_NN)=200 AGeV and kaon-proton, proton-Lambdaand pion-Cascade pairs for AuAu collisions sqrt(s_NN)=200 AGeV. They show thataverage emission space-time points of pions, kaons and protons are not thesame. These asymmetries are interpreted as a consequence of transverse radialexpansion of the system; emission time differences explain only part of theasymmetry. Therefore our measurements independently confirm the existence oftransverse radial flow. Furthermore, correlations of strange hyperons isinvestigated by performing proton-Lambda and pion-Cascade analyses, givingestimates of source size at high m_{T}. The strong interaction potentialbetween (anti-)proton and lambda as well as kaon and proton is investigated.Comment: 5 pages, 3 figures, Quark Matter 04 proceedings, submitted to J.  Phys. G: Nucl.
