چکیده

In the three-state mixing framework, considering the possible glueball components of η and η, we investigate the hadronic decays of f0(1370), f0(1500) and f0(1710) into two pseudoscalar mesons. The quarkonia-glueball content of the three states is determined from the fit to the new data presented by the WA102 Collaboration. We find that these data are insensitive to the possible glueball components of η and η. Furthermore, we discuss some properties of the mass matrix describing the mixing of the isoscalar scalar mesons. E-mail: [email protected] Mailing address 1

Scalar Glueball, Scalar Quarkonia, and their Mixing

The isosinglet scalar mesons f0(1710), f0(1500), f0(1370) and their mixing are studied. We employ two recent lattice results as the starting point; one is the isovector scalar meson a0(1450) which displays an unusual property of being nearly independent of quark mass for quark masses smaller than that of the strange, and the other is the scalar glueball mass at 1710 MeV in the quenched approxim...

Mixing of Scalar Glueball and Scalar Quarkonia

The isosinglet scalar mesons f0(1710), f0(1500), f0(1370) and their mixing are studied. Two recent lattice results are employed as the starting point; one is the approximate SU(3) symmetry in the scalar sector above 1 GeV for the connected insertion part without qq̄ annihilation, and the other is the scalar glueball mass at 1710 MeV in the quenched approximation. In the SU(3) symmetry limit, f0(...

On the Mixing of the Scalar Mesons f0(1370), f0(1500) and f0(1710)

Based on a 3 × 3 mass matrix describing the mixing of the scalar states f0(1370), f0(1500) and f0(1710), the hadronic decays of the three states are investigated. Taking into account the two possible assumptions concerning the mass level order of the bare states |N〉 = |uū + dd̄〉/ √ 2, |S〉 = |ss̄〉 and |G〉 = |gg〉 in the scalar sector, MG > MS > MN and MG > MN > MS , we obtain the glueball-quarkonia...

Scalar Meson Photoproduction

The light-quark non-strange scalar mesons a0(980), f0(980), f0(1370), a0(1450), f0(1500) and f0(1710) are of great interest as there is no generally accepted view of their structure which can encompass qqq̄q̄, molecular, qq̄ and glueball states in various combinations. It has been shown previously that the radiative decays of the scalar mesons to ρ and ω are a good probe of their structure and pro...

The mixing of the f 0 ( 1370 ) , f 0 ( 1500 ) and f 0 ( 1710 ) and the search for the scalar glueball

For the first time a complete data set of the two-body decays of the f0(1370), f0(1500) and f0(1710) into all pseudoscalar mesons is available. The implications of these data for the flavour content for these three f0 states is studied. We find that they are in accord with the hypothesis that the scalar glueball of lattice QCD mixes with the qq nonet that also exists in its immediate vicinity. ...
