Lattice EFT calculations find no resonance signature in the tetraneutron ground-state energy, only a weak attraction in the dineutron-dineutron phase shift whose confined energy is close to the experimental low-energy peak.
The manifestly Lorentz-invariant chiral EFT potential at NLO, treated non-perturbatively, yields a reasonable description of low-energy NN phase shifts and deuteron properties.

Searching for the Tetraneutron Resonance on the Lattice

Nucleon-nucleon scattering up to next-to-leading order in manifestly Lorentz-invariant chiral effective field theory: low phases and the deuteron
The manifestly Lorentz-invariant chiral EFT potential at NLO, treated non-perturbatively, yields a reasonable description of low-energy NN phase shifts and deuteron properties.
