The Wick-rotated spinor-spinor Bethe-Salpeter equation is applied to study the short distance behavior at vanishing c.m. energy and external mass. Effective interactions are fixed as particular superpositions of scalar, pseudoscalar vector and axialvector contributions. Short distance properties of

We construct weak axial one-boson exchange currents for the Bethe-Salpeter equation, starting from chiral Lagrangians of the Nβˆ†( 1236)πρa 1 Ο‰ 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
