Hard-pion current-algebra calculation of meson processes-three-point functions

Hard-pion techniques are presented for calculating vertex functions involving π,ρ,A1, and σ mesons. The development of the method involves the following assumptions: (a) saturation of intermediate sums by single mesons, (b) chiral SU(2)×SU(2) algebra commutation relations, (c) conservation of vector current, and (d) partial conservation of axial-vector current
