2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/201701Using the non-relativisitc reduction of Coulomb gauge QCD we compute spectrum of the low mass hybrid mesons containing a heavy quark-antiquark pair. The gluon degrees of freedom are treated in the mean field approximation calibrated to the gluelump spectrum. We discuss the role of the non-abelian nature of the QCD Coulomb interaction in the ordering of the spin-parity levels.12 pages, 6 figuresHigh Energy Physics - Phenomenologytext
