The quark ψψ and gluon FµνF µν vacuum expectation values are non-vanishing at low orders in αs when the perturbative ground state includes quark and gluon pairs. This offers possibilities of studying the effects of a non-trivial vacuum using formally exact perturbative methods. The QCD Feynman rules
