We investigate baryon-baryon interactions with strangeness $S=-2$ and isospinI=0 system from Lattice QCD. In order to solve this system, we prepare threetypes of baryon-baryon operators ($\Lambda-\Lambda$, $N-\Xi$ and$\Sigma-\Sigma$) for the sink and construct three source operatorsdiagonalizing the $3\times3$ correlation matrix. Combining of the prepared sinkoperators with the diagonalized source operators, we obtain nine effectiveNambu-Bethe-Salpeter (NBS) wave functions. The $3\times3$ potential matrix iscalculated by solving the coupled-channel Schr\"odinger equation. The flavorSU(3) breaking effects of the potential matrix are also discussed by comparingwith the results of the SU(3) limit calculation. Our numerical results areobtained from three sets of 2+1 flavor QCD gauge configurations provided by theCP-PACS/JLQCD Collaborations.
