Glueball Spectrum in Extended Quantum Chromodynamics

Abstract

Extended quantum chromodynamics in which the magnetic structure of the color gauge symmetry plays the important role in the dynamics is proposed as a phenomenological theory of the strong interaction. In the one-loop approximation the masses of the scalar and the axial-vector magnetic glueballs are estimated to be around 2.2 and 1.5 GeV, and the leading linear trajectory of the ${2}^{++}$ electric glueball is estimated to be ${\ensuremath{\alpha}}_{x}(s)\ensuremath{\simeq}0.48s(\mathrm{Ge}{\mathrm{V}}^{\ensuremath{-}2})+1.01$. The trajectory is proposed as the Pomeron.
