The Status of Glueballs
Calculations within QCD (lattice and sum rules) find the lightest glueball to be a scalar with mass in the range of about 1000–1700 MeV. Several phenomenological investigations are discussed which
Scalar glueball in a soft-wall model of AdS/QCD
The scalar glueball is investigated in a soft-wall model of AdS/QCD. Constraints of the mass of the scalar glueball are given through an analysis of a relation between the bulk mass and the anomalous
Scalar and tensor glueball decay rates from the Witten-Sakai-Sugimoto model
The holographic Witten-Sakai-Sugimoto model is an almost parameter-free approximation to large-N QCD with chiral quarks that in a number of cases gives surprisingly good quantitative results for
Towards the glueball spectrum from unquenched lattice QCD
A bstractWe use a variational technique to study heavy glueballs on gauge configurations generated with 2+1 flavours of ASQTAD improved staggered fermions. The variational technique includes glueball
Quenched glueballs in the DSE/BSE framework
The spectrum of glueballs with quantum numbers J = 0±+, 2±+, 3±+, 4±+ is calculated in quenched quantum chromodynamics from bound state equations. The input is taken from a parameter-free calculation
Highlights in light-baryon spectroscopy and searches for gluonic excitations
The spectrum of excited hadrons - mesons and baryons - serves as an excellent probe of quantum chromodynamics (QCD), the fundamental theory of the strong interaction. The strong coupling however
Scalar and Pseudoscalar Glueball Masses within a Gaussian Wavefunctional Approximation
The lowest scalar and pseudoscalar glueball masses are evaluated by means of the timedependent variational approach to the Yang-Mills gauge theory without fermions in the Hamiltonian formalism within
Predictions for production and decay of the pseudoscalar glueball from the Witten-Sakai-Sugimoto model
The Witten-Sakai-Sugimoto model, a top-down gauge/gravity model of large-$N_c$ low-energy QCD based on type-IIA string theory and $N_c$ D4 branes with chiral quarks added by probe D8 branes, involves

Unquenching the scalar glueball
Computations in the quenched approximation on the lattice predict the lightest glueball to be a scalar in the 1.5−1.8 GeV region. Here we calculate the dynamical effect the coupling to two
The case of the pseudoscalar glueball
Glueballs represent a key requirement of quantum chromodynamics as a non-Abelian field theory. Their search provides one of the strongest motivations for meson spectroscopy. The first glueball
The physics of glueballs
Glueballs are particles whose valence degrees of freedom are gluons and therefore in their description the gauge field plays a dominant role. We review recent results in the physics of glueballs with
Scalar glueball-qq̄ mixing above 1 GeV and implications for lattice QCD
Lattice QCD predictions have motivated several recent studies of the mixing between the predicted J = 0 glueball and a qq̄ nonet in the 1.3 → 1.7 GeV region. We show that results from apparently
Evidence for a scalar glueball
Scalar glueball and meson spectroscopy in unquenched lattice QCD with improved staggered quarks
We present results of an exploratory study of singlet scalar states in unquenched QCD using both glueball and meson operators. Results for non-singlet non-strange scalar mesons are also presented. We
Chiral suppression of scalar-glueball decay.
TLDR
It is shown that chiral symmetry implies the scalar-glueball amplitude for G0 --> qq is proportional to the quark mass, so that mixing with ss mesons is enhanced and decays to K+ K- are favored over pi+ pi-.
Identification of the glueballs and the scalar meson nonet of lowest mass
We discuss the theoretical expectations and phenomenological evidence for the lightest glueballs and the members of the meson nonet with quantum numbers J^PC=0^{++}. We reconsider the recent evidence
