Description
We note that, in the limit where the NN 1S0 and 3S1 scattering lengths, a(1S0) and a(3S1) , go to infinity, the leading terms in the effective field theory for strong NN interactions are invariant under Wigner's SU(4) spin-isospin symmetry. This explains why the leading effects of radiation pions on the S -wave NN scattering amplitudes vanish as a(1S0) and a(3S1) go to infinity. The implications of Wigner symmetry for NN→NN axion and γd→np are also considered. copyright 1999 The American Physical Society
