On the number of solutions to a crossing symmetric neutral pi - pi model
The authors determine the multiplicity of the exact solution to a crossing symmetric neutral pi - pi model. They consider only the S wave, but the multiplicity would increase by the addition of other coupled channels. The analysis is not confined to weak coupling only, and includes all solutions, in...
