Short-distance production of three particles with large scattering length
Timothy G. Backert, Sebastian Dietz, Hans-Werner Hammer +2
The short-distance production of multi-particle states in high-energy nuclear reactions provides a unique way to study the low-energy properties of few-body systems. In particular,…

Two bodies left behind
Raúl A. Briceño, Caroline S. R. Costa, Hans-Werner Hammer +1
We consider scenarios in which a shallow bound state undergoes breakup by a probe whose energy is high compared to the binding energy. The first two scenarios, which serve as warm-…

Neutron-neutron distribution of the triton from pionless EFT
Tanja Kirchner, Matthias Göbel, Hans-Werner Hammer
We compute the neutron-neutron relative-energy distribution of the triton following the hard knockout of the proton in pionless effective field theory. This distribution can be use…
