Abstract

As a first step toward clarifying whether the strange dibaryon resonances in the K̄NN-πYN system can emerge with a physical significance in the nuclear-reaction observables, we compute the break-up probability of Y_K + N → π +Σ + N at real scattering energies by solving K̄NN-πYN 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).
