چکیده

Glueballs remain an experimentally undiscovered expectation of QCD. Lattice QCD (As well as other theoretical approaches) predicts a spectrum glueballs, with the tensor (${J}^{PC}={2}^{++}$) glueball being second lightest, behind scalar glueball. Here, using chiral hadronic model, we compute decay ratios into various meson channels. We find to primarily two vector mesons, dominated by $\ensuremath{\rho}\ensuremath{\rho}$ and ${K}^{*}{K}^{*}$ These results are compared experimental data rates isoscalar mesons. Based on this comparison, make statements eligibility these mesons potential candidates: resonance ${f}_{2}(1950)$ turns out be, at present, best match predominantly

Tensor Glueball Photoproduction and Decay

Using vector meson dominance (VMD), tensor glueball photoproduction cross sections, asymmetries and widths are calculated. The predicted hadronic V V ′ decays are comparable for different vector meson (V = ρ, ω and φ) channels with the ωφ width the largest but the radiative ωγ and φγ decays are suppressed relative to ργ by over a factor of 2. This decay profile is distinct from typical meson br...

Is the graviton a domain wall glueball?

Recent developments in string theory have changed our perspective on the ancient puzzle on how to construct the QCD string. The conventional wisdom had been that the fundamental superstring for gravity operates exclusively at or near the the Planck scale with the extra 6 dimension compactified in Planckian units. The standard model (and therefore QCD) would appear as simply a low energy effecti...

TENSOR DOMINANCE AND IDENTIFICATION OF 8 (f2(1720)) AS A TENSOR GLUEBALL

The energy-momentum tensor matrix element for the tensor glueball is obtained from the tensor dominance model. Branching ration of 8(f2(1720)) in J/w radiative decay is calculated which agrees with the observed experimental branching ratio. By incorporating a soft form factor, we show that 6 (f2(1720)) has flavor independent decays to I&, qq, and XX. The very form factor is needed to understand...

Is f0(1500) a scalar glueball?

Following the discovery of two new scalar mesons, f0(1370) and f0(1500) at the Low Energy Antiproton Ring at CERN, we argue that the observed properties of this pair are incompatible with them both being QQ mesons. We show instead that f0(1500) is compatible with the ground state glueball expected around 1500 MeV mixed with the nearby states of the 0 QQ̄ nonet. Tests of this hypothesis include t...

FROM BLACK HOLES TO GLUEBALLS: The QCD3 Tensor Glueball at Strong Coupling

A strong coupling calculation of glueball masses based on the duality between supergravity and Yang-Mills theory is presented. Earlier work is extended to non-zero spin. Fluctuations in the gravitational metric lead to the 2 state on the leading Pomeron trajectory with a mass relation: m(0) < m(2) < m(1). Contrary to expectation, the mass of our new 0 state (m = 5.4573) associated with the grav...
