Description
The strongly-coupled IR region in QCD is approximated by the exchange of a phenomenological field Gμν(x) representing a color-neutral pair of dressed gluons. The Gμν acts formally as a riemannian metric, i.e. DσGμν=0. As a result, the surviving quanta are color neutral and have JP=0+, 2+, with symmetric couplings to nuclear matter - hence the IBM paradigm. The theory fixes the structure of the IBM hamiltonian. It also generates the Sp(3, R) set of symmetries of highly deformed nuclei. (orig.)
