Pseudoscalar-pseudovector equivalence of threshold production and absorption of pions

Journal Article · · Phys. Rev. Lett.; (United States)
If one compares pseudoscalar-coupled and pseudovector-coupled theories of the ..pi..NN interaction, which incorporate the restrictions of partial conservation of axial-vector current and realistic nuclear dynamics, then the amplitudes for exclusive (p,..pi../sup +/) or (..pi../sup -/,n) become identical, to O(G/sup 3/).
