THE S-MATRIX IN MESON THEORY
介子理论里的S方阵

It is shown that the divergence in the cases of pseudo-scalar mesons with pscudo-vector conpling and the charged pscudo-vector mesons with pscudo-vector coupling can be reduced to the same type as that in electrodynamics. Other types of meson theories having stronger divergence than quantum electrodynamics are also investigated. Our program of reduction is less-successful in these cases.
