The $\Lambda \Lambda$ Correlation Function in Au+Au collisions at $\sqrt{; ; ; s_{; ; ; \textrm{; ; ; NN}; ; ; }; ; ; }; ; ; $ = 200 GeV

We present ΛΛ correlation measurements in heavy-ion collisions for Au+Au collisions at sNN‾‾‾‾√=200  GeV using the STAR experiment at the Relativistic Heavy-Ion Collider. The Lednický-Lyuboshitz analytical model has been used to fit the data to obtain a source size, a scattering length and an effective range. Implications of the measurement of the ΛΛ correlation function and interaction parameters for dihyperon searches are discussed.
