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,…
Point Production of a Nonrelativistic Unparticle Recoiling Against a Particle
Eric Braaten, Hans-Werner Hammer
A nonrelativistic unparticle can be defined as an excitation created by an operator with a definite scaling dimension in a nonrelativistic field theory with an approximate conforma…
Emergence of a Bose polaron in a small ring threaded by the Aharonov-Bohm flux
Fabian Brauneis, Areg Ghazaryan, Hans-Werner Hammer +1
The model of a ring threaded by the Aharonov-Bohm flux underlies our understanding of a coupling between gauge potentials and matter. The typical formulation of the model is based…
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…
Dispersion-theoretical analysis of the electromagnetic form factors of the hyperon
Yong-Hui Lin, Hans-Werner Hammer, Ulf-G. Meißner
The electromagnetic form factors of the hyperon in the time-like region are determined precisely through a dispersion-theoretical analysis of the world data for the cross secti…
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…
