Particle representation for $NN{\bar K}$ system
In the framework of the Faddeev equations in configuration space we perform an analysis of quasi-bound state of the $NN{\bar K}$ system within a particle model. In our approach, the system $NN{\bar K}(s_{NN}=0)$ ($NN{\bar K}(s_{NN}=1))$ is described as a superposition of $ppK^{-}$ and $pn{\bar K...

| Summary: | In the framework of the Faddeev equations in configuration space we perform an analysis of
quasi-bound state of the $NN{\bar K}$ system within a particle model. In our approach, the system $NN{\bar K}(s_{NN}=0)$ ($NN{\bar K}(s_{NN}=1))$ is
described as a superposition of $ppK^{-}$ and $pn{\bar K}^0$ ($nn{\bar K}^{0}$ and $pn{ K}^-$) states, which is
possible due to a particle transition.
The relation of the particle model
to the theory of a two-state quantum system is addressed and discussed taking into
account the possibilities of deep and shallow $NN{\bar K}(s_{NN}=0)$
quasi-bound states. |
