Claims

C1strongest claim

At the studied pion mass, both the ^3S1 (deuteron) and ^1S0 (di-neutron) channels exhibit a virtual state pole, with binding energies of 6^{+5}_{-3} MeV and 11^{+6}_{-5} MeV, respectively.

C2weakest assumption

The mapping from finite-volume energies to infinite-volume scattering amplitudes via Lüscher's method (and the NPHF alternative) assumes that higher partial-wave contamination and residual finite-volume effects are under control at the volumes and energies used; this is stated in the methods section but is not independently verified by the data shown.

C3one line summary

Lattice QCD at m_pi≈292 MeV finds virtual poles in the ^3S1 and ^1S0 NN channels with binding energies 6^{+5}_{-3} MeV and 11^{+6}_{-5} MeV, extracted via Lüscher and NPHF analyses.
