The hyperon-hyperon and hyperon-nucleon interactions are important in search for exotic hadrons such dibaryon as a bound state of two baryons. Λ-Λ correlation has been measured in Au+Au collisions at √SNN = 200 GeV at RHIC-STAR experiment using high statistics data recently taken, which has been found to clearly show the anti-correlation. The first measurements of p-Ξ and Ξ-Ξ correlations in Au+Au collisions have been shown. The p-Ξ correlation function shows the strong attractive interaction, which is consistent with HAL QCD calculation. Ξ-Ξ correlation has also been measured to be negative (as anti-correlation).
