As a first step toward clarifying whether the strange dibaryon resonances in the \({\bar{K}NN-\pi YN}\) system can emerge with a physical significance in the nuclear-reaction observables, we compute the break-up probability of \({Y_K + N \to \pi +\Sigma + N}\) at real scattering energies by solving \({\bar{K}NN-\pi YN}\) coupled-channel Alt–Grassberger–Sandhas equations. We examine how the signature of the dibaryon resonance shows up in the probability, and also discuss the possibility for a use of strange dibaryon production reactions to distinguish two-body-interaction models with Λ(1405).
