Nuclear system with antikaons, so-called kaonic nuclei, has been a longstanding issue in strange nuclear physics and hadron physics, because they might have exotic nature; In particular, they could be a doorway to the dense matter due to…

We report a theoretical study of the $pp\to p K^+\Lambda(1405)$ reaction, which was recently investigated at COSY-J\"{u}lich by using a 3.65 GeV/c circulating proton beam incident on an internal hydrogen target. The reaction is driven by…

The Faddeev AGS equations are solved for coupled-channels $\bar{K}NN-\pi\Sigma{N}$ system with quantum numbers $I=1/2$ and $S=0$. Using separable potentials for $\bar{K}N-\pi\Sigma$ interaction, we have calculated the transition probability…
