Efimov Physics around the neutron rich Calcium-60 isotope
G. Hagen, P. Hagen, H. -W. Hammer +1
We calculate the neutron-Calcium-60 S-wave scattering phase shifts using state of the art coupled-cluster theory combined with modern ab initio interactions derived from chiral eff…
Charge form factors of two-neutron halo nuclei in halo EFT
P. Hagen, H. -W. Hammer, L. Platter
We set up a formalism to calculate the charge form factors of two-neutron halo nuclei with S-wave neutron-core interactions in the framework of the halo effective field theory. The…
Renormalization in the Three-body Problem with Resonant P-wave Interactions
Eric Braaten, P. Hagen, H. -W. Hammer +1
Resonant P-wave interactions can be described by a minimal zero-range model defined by a truncated effective range expansion, so that the only 2-body interaction parameters are the…
Two- and three-body structure of the Y(4660)
P. Hagen, H. -W. Hammer, C. Hanhart
We study general features of three-meson bound states using the Y(4660) as an example. Here the Y(4660) is assumed to be either a two-body bound state of the f_0(980), itself a bou…
