Possible bound state and its -channel formation in the reaction

Sekihara, Takayasu; Fujioka, Hiroyuki*; Ishikawa, Takatsugu*

We theoretically investigate a possibility of an bound state and its formation in the reaction. First, in the fixed center approximation to the Faddeev equations we obtain an bound state with a binding energy of 25 MeV and width of 19 MeV, where we take the interaction with a coupling to the channel from the linear model. Then, in order to investigate the feasibility from an experimental point of view, we calculate the cross section of the reaction at the photon energy in the laboratory frame around 1.2 GeV.
