New Glueball-Meson Mass Relations
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 G...
متن کاملof meson , hybrid , and glueball states
The effective QCD Hamiltonian is constructed with the help of the background perturbation theory, and relativistic Feynman–Schwinger path integrals for Green's functions. The resulting spectrum displays mass gaps of the order of one GeV, when additional valence gluon is added to the bound state. Mixing between meson, hybrid, and glueball states is defined in two ways: through generalized Green'...
متن کاملThe J Pc = 0 ++ Scalar Meson Nonet and Glueball of Lowest Mass
The evidence for the low mass J = 0 states is reconsidered. We suggest classifying the isoscalars f0(980) and f0(1500) as members of the 0 ++ nonet, with a mixing rather similar to that of the pseudoscalars η′ and η. The broad state called f0(400− 1200) or “sigma” and the state f0(1370) are considered as different signals from a single broad resonance, which we take to be the lowest-lying 0 glu...
متن کاملNew Mass Relation for Meson 25-plet
By assuming the existence of (quasi)-linear Regge trajectories for 25-plet mesons in the low energy region, we derive a new, 14th power, meson mass relation. This relation may be reduced to a quadratic Gell-Mann–Okubo type formula by fitting the values of the Regge slopes of these (quasi)-linear trajectories. Such a formula holds with an accuracy of ∼ 2% for vector mesons, and E-mail: BURAKOV@P...
متن کاملGlueball Mass Spectrum from Supergravity∗
We review the calculation of the spectrum of glueball masses in non-supersymmetric Yang-Mills theory using the conjectured duality between supergravity and large N gauge theories. The glueball masses are obtained by solving the supergravity wave equations in a black hole geometry. The glueball masses found this way are in unexpected agreement with the available lattice data. We also show how to...
