ABSSM - a new field-theoretic method of describing scattering/production processes of composite particles by asymptotic in-/outgoing Bethe-Salpeter states

F. Kleefeld

A new relativistic field-theoretic formalism called "Asymptotic Bethe-Salpeter State Method" (ABSSM) is presented, which allows to calculate both electromagnetic formfactors and ha…
