We construct weak axial one-boson exchange currents for the Bethe-Salpeter equation, starting from chiral Lagrangians of the N∆( 1236)πρa 1 ω 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 equ
Using modern data, we first refit constants needed to complete an anomalous πρωa 1 Lagrangian obtained within the approach of hidden local symmetries. Then we derive from this Lagrangian electromagnetic isoscalar ρπγ and ρa 1 γ exchange currents needed in calculations of the deuteron electromagnetic
