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 αΛ Λ = - 0.10,-2.37 + 0.45,0.0 and effective range Λ, = 13.90<-13.90>+16.10, ,9.48fm 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.
