“…Constituent gluon models for hybrids were introduced by Horn and Mandula [83] and were subsequently developed by Iddir et al and Ishida et al [84][85][86]. Since these models assume a diagonal gluon angular momentum g their predictions for quantum numbers differ somewhat from other models.…”

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.

“…[73]) cannot make Π g or Σ u states while three dimensional "bead" models (Ref. [83]) cannot make Σ + states. Thus including gluon spin is a minimal necessity in this class of models (although the level ordering problem must be overcome as discussed above).…”

“…Hybrid states have been studied in various approaches such as the flux tube model [10,11,12,13,14], the constituent gluon model [15,16,17], the QCD sum rule [18] and the lattice QCD [19]. In the following, we will argue the mysterious Y (2175) could be a 1 −− strangeonium hybrid (ssg) from the flux tube model and the constituent gluon model.…”

“…Close et al, improved the previous treatments using a Hamiltonian Monte Carlo algorithm, they predicted that the mass of the lightest ssg hybrid is 2.1-2.2GeV [11], which is consistent with experimental value of Y (2175)(m = 2.175 ± 0.010 ± 0.015GeV). In the constituent gluon model, a hybrid state is a quark-antiquark state with an additional constituent gluon, such a meson would decay though gluon dissociation into a qq pair [15,16,17]. The constituent gluon is expected to add 0.7 ∼ 1GeV to the corresponding quarkonia and the excitation energy is about 0.4 GeV for the excited hybrid state, naively the mass of the ssg would be about 2.12-2.42GeV, which is also consisitent experimental data of Y (2175).…”

We propose that the recently observed structure at 2175MeV by the Babar Collaboration is a 1 −− strangeonium hybrid, and we investigate this interpretation from both the flux tube model and the constituent gluon model. The decay patterns and decay width in the flux tube model and the constituent gluon model (for the "gluon excited" hybrid) are very similar. The tetraquark hypothesis is not favored by the available experimental data. The crucial test of our scenario is suggested, furthermore, the promising channels which can discriminate the hybrid interpretation from the tetraquark are also suggested.

“…The flux tube model extends this bag model list by adding a degenerate set with reversed {P,C) to the lowest hybrid multiplet. Constituent gluon models of hybrids differ in that their lowest hybrid multiplet has P-wave qij quantum numbers [27] and so is nonexotic, although exotics appear in excited hybrid multiplets. An investigation of qijg interpolating fields [28] shows that hybrids can have any Jpc.…”

In this pedagogical review we discuss the theoretical understanding of light hadron spectroscopy in terms of QCD and the quark model. We begin with a summary of the known and surmised properties of QCD and confinement. Following this we review the nonrelativistic quark potential model for qij mesons and discuss the quarkonium spectrum and methods for identifying qq states. Finally we review theoretical expectations for non-qij states (glueballs, hybrids and multiquark systems) and the status of experimental candidates for these states.
