    "abstract": "We analyze the invariant mass spectrum of Lambda-Lambda in $^{12}C(K^-,K^+\nLambda Lambda)$ reaction at P(K^+)=1.65 GeV/c by using a combined framework of\nIntraNuclear Cascade (INC) model and the correlation function technique. The\nobserved enhancement at low-invariant masses can be well reproduced with\nattractive Lambda-Lambda interactions with the scattering length either in the\nrange a = -6 \\sim -4 fm (no bound state) or a = 7 \\sim 12 fm (with bound\nstate). We also discuss Lambda-Lambda correlation functions in central\nrelativistic heavy-ion collisions as a possible way to eliminate this discrete\nambiguity.",
