Instantaneous Bethe-Salpeter Equation: (Semi-)Analytical Solution
arXiv:hep-ph/0010078
Abstract
The Bethe-Salpeter equation for bound states of a fermion-antifermion pair in the instantaneous approximation for the involved interaction kernel is converted into an equivalent matrix eigenvalue problem with explicitly (algebraically) given matrices.
