Abstract

Abstract We use an existing model of the

three-body system based on two-body separable interactions to study the

three-body channel. For the

, and

amplitudes, we have constructed separable potentials based on the most recent results of the HAL QCD Collaboration. They are characterized by the existence of a resonance just below or above the

threshold in the H-dibaryon channel,

. A three-body resonance appears 2.3 MeV above the

threshold. We show that if the

H-dibaryon channel is not considered, the

S wave resonance disappears. Thus, the possible existence of a

resonance would be sensitive to the

interaction. The existence or nonexistence of this resonance could be evidenced by measuring, for example, the

cross section.
