In a recent JLab 3H(e,e′K+) experiment a structure near the ΣNN threshold was observed, which was interpreted to be a T = 1 resonance. Using separable NN and ΛN−ΣN potentials in the Faddeev equations, we demonstrate that it is possible that both T = 0 and T = 1 resonances may have been excited. Moreover, their pole positions, in our model calculation, are sufficiently close to one another that it is unlikely that these resonances in the ΣNN spectrum can be resolved.
