Abstract

JLab has recently found indications of the possible existence of a (Formula presented.) resonance at (Formula presented.) MeV. In the past, using models that exploit symmetries between the two-baryon sector with and without strangeness, hyperon–nucleon interactions that reproduce the experimental data of the strangeness (Formula presented.) sector have been derived. We make use of these interactions to review the existing Faddeev studies of the (Formula presented.) system that show theoretical evidence of a (Formula presented.) (Formula presented.) quasibound state near the threshold. The calculated position of the pole is at 2.92 (Formula presented.) 2.17 MeV, which is in reasonable agreement with the experimental findings.
