چکیده

Using the “glueball dominance” picture of the mixing between qq̄ mesons of different hidden flavors, we establish new glueball-meson mass relations which serve as a basis for glueball spectral systematics. For the tensor glueball mass 2.3 ± 0.1 GeV used as an input parameter, these relations predict the following glueball masses: M(0) ≃ 1.65 ± 0.05 GeV, M(1) ≃ 3.2 ± 0.2 GeV, M(2) ≃ 2.95 ± 0.15 GeV, M(3) ≃ 2.8 ± 0.15 GeV. We briefly discuss the failure of such relations for the pseudoscalar sector. Our results are consistent with (quasi)-linear Regge trajectories for glueballs with slope ≃ 0.3 ± 0.1 GeV.

Glueball Spectroscopy in Regge Phenomenology *

We show that linear Regge trajectories for mesons and glueballs, and the cubic mass spectrum associated with them, determine a relation between the masses of the ρ meson and the scalar glueball, M (0 ++) = 3/ √ 2 M (ρ), which implies M (0 ++) = 1620 ± 10 MeV. We also discuss relations between the masses of the scalar and The existence of a gluon self-coupling in QCD suggests that, in addition t...

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 use Asqtad improved staggered fermions and gauge configurations generated by the MILC collaboration at lattice spacings of .12 and .09 fm. In this formulation, the glueball mass is not significantl...

Glueball Masses from Supergravity with Flavor

We study the glueballs in a four-dimensional N = 2 super YangMills theory with fundamental matters in terms of the supergravity dual. The supergravity background is constructed by N D3 brane with a probe D7 brane. We numerically compute the glueball masses for 0++ and 1 in the background. We find that the mass ratio of 0++ glueballs is mostly in agreement with the lattice calculations. We compa...

Glueball masses and Pomeron trajectory in nonperturbative QCD approach

Using a nonperturbative method based on asymptotic behaviour of Wilson loops we calculate masses of glueballs and corresponding Regge–trajectories. The method contains no fitting parameters and the mass scale is fixed by the meson Regge slope. Theoretical predictions for lowest glueball states are in a perfect agreement with lattice results. The leading glueball trajectory and its relation to t...

Glueballs, Hybrids, Multiquarks. Experimental facts versus QCD inspired concepts.

Glueballs, hybrids and multiquark states are predicted as bound states in models guided by quantum chromodynamics, by QCD sum rules or QCD on a lattice. Estimates for the (scalar) glueball ground state are in the mass range from 1000 to 1800MeV, followed by a tensor and a pseudoscalar glueball at higher mass. Experiments have reported evidence for an abundance of meson resonances with 0−+, 0 an...
