| Abstract | In the Coulomb gauge of nonablian gauge theories there are in general, in individual graphs, 'energy-divergences' on integrating over the loop energy variable for fixed loop momentum. These divergences are avoided in the Hamiltonian, phase-space formulation. But, even in this formulation, energy-divergences reappear at 2-loop order. We show in an example how these cancel between graphs as a consequence of Ward identities. |
