Gluelump spectrum from Coulomb gauge QCD
arXiv:0707.3156 · doi:10.1103/PhysRevD.77.056005
Abstract
We compute the energy spectrum of gluelumps defined as gluonic excitations bound to a localized, static octet source. We are able to reproduce the nontrivial ordering of the spin-parity levels and show how this is related to the non-abelian part of the Coulomb interaction between color charges.
