“…Finally, we present the results of a recent exhaustive computation of the light meson spectrum by the Hadron Spectrum Collaboration [38]. This computation was made with a large operator basis, on lattice of size 16 3 × 128 up to 24 3 × 128 lattice, a temporal lattice spacing around 0.034 fm and a spatial lattice spacing of approximately 0.12 fm, and pion masses of 702, 524, and 391 MeV.…”

A review of the theoretical and experimental status of hybrid hadrons is presented. The states π 1 (1400), π 1 (1600), and π 1 (2015) are thoroughly reviewed, along with experimental results from GAMS, VES, Obelix, COMPASS, KEK, CLEO, Crystal Barrel, CLAS, and BNL. Theoretical lattice results on the gluelump spectrum, adiabatic potentials, heavy and light hybrids, and transition matrix elements are discussed. These are compared with bag, string, flux tube, and constituent gluon models. Strong and electromagnetic decay models are described and compared to lattice gauge theory results. We conclude that while good evidence for the existence of a light isovector exotic meson exists, its confirmation as a hybrid meson awaits discovery of its iso-partners. We also conclude that lattice gauge theory rules out a number of hybrid models and provides a reference to judge the success of others.

“…Over the last few years, through the development of a combination of novel techniques, we have made significant progress in using lattice QCD to compute spectra of excited light isovector [5,6] and isoscalar [7,8] mesons, charmonia [2] and open-charm mesons [4]. Figs.…”

I report on some recent progress in studying heavy and light hadrons using lattice QCD. Results from calculations of excited charmonia and open-charm mesons are discussed where novel techniques have enabled the extraction of extensive spectra, including states with exotic quantum numbers and non-exotic hybrids, with high statistical precision; the interesting phenomenology suggested by these results will be highlighted. I then discuss investigations of unstable states on the lattice, concentrating on a study which mapped out the energy-dependence of the ρ resonance in ππ scattering. Computations of spectra of excited light, strange and charmed baryons are also mentioned and some implications of the results discussed.
