I have the following contour integral form of Wick's theorem (C indicating contraction):(adsbygoogle = window.adsbygoogle || []).push({});

[tex]C[A(z):BC:(w)]=\frac{1}{2 \pi i} \int _w \frac{dx}{x-w} C[A(z)B(x)]C(w) + B(x)C[A(z)C(w)][/tex]

Does anybody know how to evaluate contractions like C[:AB:(z)C(w)]?
