Resolving temporal Gribov copies in Coulomb gauge Yang-Mills theory

Understand

The continuum Yang-Mills functional integral within the first order formalism and in Coulomb gauge is studied.

• In particular, the temporal zero-modes of the Faddeev-Popov operator are explicitly accounted for.
• It is shown that the treatment of these zero-modes results in the constraint that the total color charge of the system vanishes at all times.
• Further, it is argued that the functional integral is effectively fully gauge-fixed once Gauss' law has been resolved in Coulomb gauge.
