Chromo-Electric flux tubes

Abstract

The profiles of the chromo-electric field generated by static quark-antiquark, $Q\bar{Q}$ and three-quark, $QQQ$ sources are calculated in Coulomb gauge. Using a variational ansatz for the ground state, we show that a flux tube-like structure emerges and combines to the ``Y''-shape field profile for three static quarks. The properties of the chromo-electric field are, however, not expected to be the same as those of the full action density or the Wilson line and the differences are discussed.
