Axial-vector form factors from current algebra Regge poles and Veneziano model

Considering the following processes axial current + nucleon → vector current + nucleon, axial current + pion → vector current + σ-meson, and making use of current algebra identities and the Regge model, an asymptotic expression is obtained for the axial-vector form factors of the nucleon and the pio...
