Glueball calculations in large-Nc gauge theory
Abstract
We use the light-front Hamiltonian of transverse lattice gauge theory to compute from first principles the glueball spectrum and light-front wavefunctions in the leading order of the 1/Nc colour expansion. We find 0++, 2++, and 1+- glueballs having masses consistent with Nc=3 data available from Euclidean lattice path integral methods. The wavefunctions exhibit a light-front constituent gluon structure.
