Abstract

We determine ΛΛ scattering parameters from a ΛΛ invariant mass spectrum that was obtained by ¹²C(K^-, K⁺ΛΛ) reaction at the KEK Proton Synchrotron. In the framework of Watson's procedure, the obtained scattering length a _ΛΛ = -0.10 ^+0.45_-2.37 ± 0.04 and effective range r_ΛΛ =13.90 ^>_<^+16.10_-13.90 ± 9.48 fm are most consistent with the values predicted by using the Nijmegen soft core models (NSC97's). However, the predicted values by using the Nijmegen hard-core ND (G-matrix) and the extended soft-core (ESC00) models are out of two standard deviations from the determined scattering parameters.
