Stability in the instantaneous Bethe-Salpeter formalism: reduced exact-propagator bound-state equation with harmonic interaction
Z. -F. Li, Wolfgang Lucha, F. Schoberl
Several numerical investigations of the Salpeter equation with static confining interactions of Lorentz-scalar type revealed that its solutions are plagued by instabilities of pres…

Stability of the Solutions of Instantaneous Bethe-Salpeter Equations with Confining Interactions
Wolfgang Lucha, F. Schoberl
For two bound-state equations derived as simplified forms of the Bethe-Salpeter equation with confining interaction, stability of all solutions is rigorously shown.

Stability of Salpeter Solutions
Wolfgang Lucha, F. Schoberl
In the framework of instantaneous approximations to the Bethe-Salpeter formalism for the description of bound states within quantum field theories, depending on the Lorentz structu…
