摘要：

The pion-pion scattering amplitudes provided by second-order chiral perturbation theory are confronted with known rigorous constraints derived from the axioms of quantum field theory. We mainly test constraints restricting the π0π0 S- and D-wave amplitudes in the unphysical interval 0≤s≤4mπ2. These constraints impose significant lower bounds for a linear combination of coupling constants specifying the second-order chiral Lagrangian. The accepted value of this combination is consistent with these bounds. The π0-π0 S and D waves are strongly correlated by a set of constraints. © 1995 The American Physical Society.
