ABSSM - a new field-theoretic method of describing scattering/production processes of composite particles by asymptotic in-/outgoing Bethe-Salpeter states
F. Kleefeld
Abstract
A new relativistic field-theoretic formalism called "Asymptotic Bethe-Salpeter State Method" (ABSSM) is presented, which allows to calculate both electromagnetic formfactors and hadronic scattering and production amplitudes of elementary and composite systems (being described by Bethe-Salpeter amplitudes) within one theoretical framework. The ABSSM is then applied to the deuteron as a composite system of two nucleons.
