Editing Color confinement (section)

==Models of fully screened quarks==
Besides the quark confinement idea, there is a potential possibility that the color charge of quarks gets fully screened by the gluonic color surrounding the quark. Exact solutions of SU(3) classical [[Yang–Mills theory]] which provide full screening (by gluon fields) of the color charge of a quark have been found.<ref name="Cahill 1978">
