Abstract Mass ratios of glueballs predicted by the latest lattice QCD calculations in the quenched approximation agree well with four prime experimental candidates. 
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 glueballExpand
Glueball spectrum from a potential model
The spectrum of two-gluon glueballs below 3 GeV is investigated in a potential model with a dynamical gluon mass using the variational method. The short-distance potential is approximated byExpand
Glueballs and mesons: The ground states
We provide a new, independent, and analytic estimate of the lowest glueball mass, and we found it at 1661 MeV within a relativistic quantum-field model based on analytic confinement. The conventionalExpand
Glueball masses and Regge trajectories for the QCD-inspired potential
The bound state of two massive constituent gluons is studied in the potential approach. The relativistic quasi-classical wave equation with the QCD-inspired scalar potential is solved by theExpand
Scalar mesons and glueballs in D-p-D-q hard-wall models
We investigate the light scalar mesons and glueballs in the Dp-Dq hard-wall models, including D3-Dq, D4-Dq, and D6-Dq systems. It is found that only in the D4-D6 and D4-D8 hard-wall models are theExpand
Glueball hunting in e+e−→J/ψ→φf0
Abstract Building on recent work by Brodsky et al., we advocate searching for glueball degrees of freedom in e + e − → J / ψ → φf 0 at CLEO-c and BES.
Determination of the glueball mass spectrum with allowance for spin-orbital interactions
The mass spectrum of a coupled state is analytically determined. The mechanism of production of a constituent mass of particles forming a coupled state is explained. The change of the coupled stateExpand
Casimir scaling, glueballs, and hybrid gluelumps
Abstract.Assuming that the Casimir scaling hypothesis is well verified in QCD, masses of glueballs and hybrid gluelumps (gluon attached to a point-like c¯ pair) are computed within the framework ofExpand
Hadron spectrum and infrared-finite behavior of QCD running coupling
We study the behavior of the QCD effective coupling αs in the low-energy region by exploiting the conventional meson spectrum within a relativistic quantum-field model based on analytical confinementExpand
Glueball spectrum based on a rigorous three-dimensional relativistic equation for two-gluon bound states. I. Derivation of the relativistic equation
A rigorous three-dimensional relativistic equation satisfied by two-gluon bound states is derived from the QCD with massive gluons. With the gluon fields and the quark fields being expanded in termsExpand


Glueball mass predictions of the valence approximation to lattice QCD
We evaluate the infinite volume, continuum limit of glueball masses in the valence (quenched) approximation to lattice QCD. For the lightest scalar and tensor states we obtain masses ofExpand
Dynamics of glueball and qq̄ production in the central region of pp collisions
Abstract We explain the φ and t dependences of mesons with J PC =0 ±+ ,1 ++ ,2 ±+ produced in the central region of pp collisions. For the 0 ++ and 2 ++ sector this reveals a systematic behaviour inExpand
Scalar quarkonium masses and mixing with the lightest scalar glueball
We evaluate the continuum limit of the valence (quenched) approximation to the mass of the lightest scalar quarkonium state for a range of different quark masses and to the mixing energy betweenExpand
Numerical evidence for the observation of a scalar glueball.
We compute from lattice QCD in the valence (quenched) approximation the partial decay widths of the lightest scalar glueball to pairs of pseudoscalar quark-antiquark states. These predictions andExpand

It is shown that f0(1500) is compatible with the ground state glueball expected around 1500 MeV mixed with the nearby states of the 0 ++ Q ¯ state. Expand
G(1590)-Meson and possible characteristic features of a glueball
AbstractThe scalar mesonG(1590) is considered as a possible glueball. The decay mechanism, characteristic of a glueball, is proposed (the discolouring of gluons by gluons) which allows one toExpand
A comprehensive lattice study of SU(3) glueballs
