Gauge-invariant fields in the temporal gauge, Coulomb-gauge fields, and the Gribov ambiguity (English)
0 references
A relationship between the gauge-invariant temporal-gauge and the Coulomb-gauge formulations of two-color QCD is established.The temporal gauge Hamiltonian is expressed in terms of gauge-invariant fields and it is shown that it can be interpreted as a sum of the Coulomb-gauge Hamiltonian and another part that is important for determining the equations of motion of temporal gauge fields. The multiplicities of gauge-invariant temporal gauge fields that belong to different topological sectors are also discussed and it is shown that these multiplicities of gauge invariant fields are manifestations of Gribov ambiguity.
