| Abstract: | The QCD trace anomaly motivates the consideration of a low energy glueball-gluon coupling . We point out that this should constitute the leading kinetic term for the gluons at low energies. Anti-screening of the gluons by the glueball then induces a classical Coulomb potential of color charges which increases at large distances and motivates the inclusion of a corresponding term in the inter-quark potential.
