description | An $\bar N$N¯N potential is reviewed which has been derived within chiral effective field theory by the Jülich-Bonn group. By construction it reproduces $\bar N$N¯N phase shifts and inelasticities, provided by an elaborate phase-shift analysis of available $\bar p$p¯p scattering data. This interaction is then employed in a study of neutron-antineutron oscillations in the deuteron. In particular, the deuteron lifetime is considered, and results for it are presented in terms of the free-space n – $\bar n$n¯ oscillation time, based on that $\bar N$N¯N potential in combination with an NN interaction likewise derived within chiral effective field theory. |
