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…
Structure and EM form factors of purely relativistic systems
V. A. Karmanov, J. Carbonell, H. Sazdjian
The Bethe-Salpeter equation for two massive scalar particles interacting by scalar massless exchange has solutions of two types, which differ from each other by their behavior in t…
Power Counting in Peripheral Partial Waves: The Singlet Channels
M. Pavón Valderrama, M. Sánchez Sánchez, C. -J. Yang +3
We analyze the power counting of the peripheral singlet partial waves in nucleon-nucleon scattering. In agreement with conventional wisdom, we find that pion exchanges are perturba…
Current conservation in electrodisintegration of a bound system in the Bethe-Salpeter approach
V. A. Karmanov, J. Carbonell
Using our solutions of the Bethe-Salpeter equation with OBE kernel in Minkowski space both for the bound and scattering states, we calculate the transition form factors for electro…
Scattering states in Bethe-Salpeter equation
V. A. Karmanov, J. Carbonell
The off-mass shell scattering amplitude, satisfying the Bethe-Salpeter equation for spinless particles in Minkowski space with the ladder kernel, is computed for the first time.
