Signature of Strange Dibaryon in Kaon-Induced Reaction

We examine how the signature of the strange-dibaryon resonances in the ${\bar{K}NN}$ –πΣ N system shows up in the scattering amplitude on the physical real energy axis within the framework of Alt–Grassberger–Sandhas equations. The so-called point method is applied to handle the three-body unitarity cut in the amplitudes. We also discuss the possibility that the strange-dibaryon production reactions can be used for discriminating between existing models of the two-body ${\bar{K}N}$ –πΣ system with Λ(1405).
