Electromagnetic form factor via Minkowski and Euclidean Bethe-Salpeter amplitudes
V.A. Karmanov, J. Carbonell1, M. Mangin-Brinet1
(2008)

The electromagnetic form factors calculated through Euclidean Bethe-Salpeter amplitude and through the light-front wave function are compared with the one found using the Bethe-Salpeter amplitude in Minkowski space. The form factor expressed through the Euclidean Bethe-Salpeter amplitude (both within and without static approximation) considerably differs from the Minkowski one, whereas form factor found in the light-front approach is almost indistinguishable from it.
