STATUS-QUO OF THE COULOMB GAUGE - PROBLEMS AND A POSSIBLE REMEDY

A new method, called split dimensional regularization, is discussed to regulate the energy-integrals in non-Abelian theories in the Coulomb gauge. The technique leads to unambiguous integrals, some of which are nonlocal, and is tested to one loop by computing the Yang-Mills self- energy, as well as the quark self-energy Sigma(p), and the quark-quark -gluon vertex Lambda(mu). It turns out that the Yang-Mills self-energy is local, but nontransverse, and that ghosts play an important role i n the BRST identities.
