Glueballs and Hybrid Mesons
Chris Michael
Abstract
The status of non-perturbative QCD calculations for mesons with gluonic excitation is presented. Lattice results for the glueball spectrum are reviewed. For hybrid mesons, the heavy quark results are summarised and new results are presented for light quarks. Preliminary results for the spectrum of light-quark hybrid mesons indicate substantial mixing with quark model states for non-exotic JPC. For the exotic JPC hybrid mesons, the JPC=1-+, 0+- and 2+- states are explored.
