An alternative scheme for pionless EFT: neutron-deuteron scattering in the doublet S-wave
M. Ebert, H. -W. Hammer, A. Rusetsky
Using the effective-range expansion for the two-body amplitudes may generate spurious sub-threshold poles outside of the convergence range of the expansion. In the infinite volume,…
Weak decay of halo nuclei
Wael Elkamhawy, Hans-Werner Hammer, Lucas Platter
We investigate the weak decay of one-neutron halo nuclei into the proton-core continuum, i.e., beta-delayed proton emission from the halo nucleus using a cluster effective field th…
Final-state interactions and spin structure in breakup of Li in Halo EFT
Matthias Göbel, Bijaya Acharya, Hans-Werner Hammer +1
We calculate the breakup of the halo nucleus Li in Halo Effective Field Theory (Halo EFT) at leading order. In Halo EFT, Li is treated as a three-body syste…
Halo EFT for Ne in a spherical formalism
Wael Elkamhawy, Hans-Werner Hammer
We calculate the electromagnetic properties of the deformed one-neutron halo candidate Ne using Halo Effective Field Theory (Halo EFT). In this framework, Ne is bound…
Theory of Halo Nuclei
H. -W. Hammer
Halo nuclei are characterized by a few weakly bound halo nucleons and a more tightly bound core. This separation of scales can be exploited in a few-body description of halo nuclei…
Three-body resonances in pionless effective field theory
Sebastian Dietz, Hans-Werner Hammer, Sebastian König +1
We investigate the appearance of resonances in three-body systems using pionless effective field theory at leading order. The Faddeev equation is analytically continued to the unph…
