Neutron transfer reactions in halo effective field theory
M. Schmidt, L. Platter, H. -W. Hammer
Direct reaction experiments provide a powerful tool to probe the structure of neutron-rich nuclei like beryllium-11. We use halo effective field theory to calculate the cross secti…
Halo structure of C
Jonas Braun, Hans-Werner Hammer, Lucas Platter
C has three states below the C + threshold with quantum numbers . These states have relatively small neutron separation energies compared t…
Signatures of few-body resonances in finite volume
P. Klos, S. König, H. -W. Hammer +2
We study systems of bosons and fermions in finite periodic boxes and show how the existence and properties of few-body resonances can be extracted from studying the volume dependen…
Threshold Effects and the Line Shape of the X(3872) in Effective Field Theory
M. Schmidt, M. Jansen, H. -W. Hammer
Latest measurements suggest that the X(3872) mass lies less than 200 keV away from the D0-Dbar0* threshold, reenforcing its interpretation as a loosely-bound mesonic molecule. This…
Electric structure of shallow D-wave states in Halo EFT
J. Braun, W. Elkamhawy, R. Roth +1
We compute the electric form factors of one-neutron halo nuclei with shallow D-wave states up to next-to-leading order and the E2 transition from the S-wave to the D-wave state up…
