Abstract:
At energies lower than the deuteron breakup, the doublet neutron-deuteron elastic scattering is known to have a virtual state and a zero in the amplitude just below the elastic threshold. We formulate a halo/cluster effective field theory that incorporates both physics and their behavior as the deuteron binding energy decreases. We tune the neutron-neutron and neutron-proton scattering lengths towards the unitarity limit and demonstrate, in a model-independent way, the nature of the virtual state as an excited Efimov state.
