手征不变的有效拉格朗日量可以用来计算低能π介子和核子之间的三体相互作用。用π-核散射长度的计算说明了这种方法。
A chiral invariant effective lagrangian may be used to calculate the three-body interactions among low-energy pions and nucleons in terms of known parameters. This method is illustrated by the calculation of the pion-nucleus scattering length.
