Weak axial exchange currents for the Bethe-Salpeter equation

Creators

Description

We construct weak axial one-boson exchange currents for the Bethe-Salpeter equation, starting from chiral Lagrangians of the NΔ(1236)πρa1ω system. The currents fulfill the Ward-Takahashi identities and the matrix element of the full current between the two-body solutions of the Bethe-Salpeter equation satisfies the PCAC constraint exactly
