Purely virtual extension of quantum field theory for gauge invariant fields: Yang–Mills theory
Abstract We extend quantum field theory by including purely virtual “cloud” sectors, to define physical off-shell correlation functions of gauge invariant quark and gluon fields, without affecting the S matrix amplitudes. The extension is made of certain cloud bosons, plus their anticommuting partne...
