摘要：
In the Coulomb gauge of QCD. the Hamiltonian contains a nonlinear Christ-Lee term, which may alternatively be derived from a careful treatment of ambiguous Feynman integrals at 2-loop order. We investigate how and if UV divergences from higher order graphs can be consistently absorbed by renormalization of the Christ-Lee term. We find that they cannot. (C) 2010 Elsevier Inc.
