Gluelump Spectrum on Coulomb Gauge QCD

ORAL

Abstract

We compute the energy spectrum of low-lying gluonic excitations in the presence of static quark-antiquark octet color sources at zero separation using Coulomb gauge and the quasi-particle representation. The states also refer to gluelump states. We will show how does many-body interactions from non-abelian Coulomb kernel generate correct ordering of spectrum for spin-parity-charge conjugation multiplets.
