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(...
متن کاملScalar 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...
متن کاملGlueball-quarkonia content of the f0(1370
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 , the glueball-quarkonia content of ...
متن کاملScalar nonet quarkonia and the scalar glueball: mixing and decays in an effective chiral approach
We study the strong and electromagnetic decay properties of scalar mesons above 1 GeV within a chiral approach. The scalar-isoscalar states are treated as mixed states of quarkonia and glueball configurations. A fit to the experimental mass and decay rates listed by the Particle Data group is performed to extract phenomenological constraints on the nature of the scalar resonances and to the iss...
