A Λnn three-body resonance
We solved the Faddeev equations in the Λnn system Jπ = ½+, T = 1). There is no bound state but found a resonance state. Complex Energy Method helps to find the location of the resonance energy in the complex Riemann sheet. We obtained a resonance energy E = 0.25 − 0.40i MeV using the realistic NN an...
