Lepton-neutron interaction and S-wave low energy parameters
Jaume Carbonell, Tobias Frederico
A lepton-neutron potential in configuration space is obtained. It is based on the Coulomb plus hyperfine interaction Hamiltonian integrated over the neutron charge and magnetic den…

Abnormal solutions of Bethe--Salpeter equation with massless and massive exchanges
Jaume Carbonell1, Vladimir Karmanov, Ekaterina Kupriyanova +1
We summarize the main properties of the so called ''abnormal solutions'' of the Wick--Cutkosky model, i.e. two massive scalar particles interacting via massless scalar exchange ("p…
