Can Tetraneutron be a Narrow Resonance?

NUCLEAR STRUCTURE ⁴NN; analyzed available data; calculated evolution of the energy and width of the four-neutron system with the scaling of the N3LO interaction; deduced the energy of the four-neutron system compatible with the experimental value, its width must be larger than the reported upper limit, supporting the interpretation of the experimental observation as a reaction process too short to form a nucleus. Quasistationary formalism using ab initio techniques with various two-body chiral interactions.
