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…

Exact-propagator instantaneous Bethe-Salpeter equation for quark-antiquark bound states
Z. -F. Li, Wolfgang Lucha, F. F. Schoberl
Recently, an instantaneous approximation to the Bethe-Salpeter formalism for the analysis of bound states in quantum field theory has been proposed which retains, in contrast to th…
