A Problem Is there any way to calculate <0|F(x)F(y)|0>, where F(x) is the non-Abelian field strength? Thanks!

Re: A Problem I wonder if we can easily get <0|F(x)F(y)|0> from <0|A(x)A(y)|0>.

Re: A Problem Should be proper to write it <0|Tr(F(x)F(y))|0>. Isn't it easier to begin with the Abelian <0|F(x)F(y)|0>?
