چکیده
In this article, we take the point of view that the scalar mesons f0(980) and a0(980) are diquark-antidiquark states (qq)3̄(q̄q̄)3, and devote to determine their masses in the framework of the QCD sum rules approach with the interpolating currents constructed from scalar-scalar type and pseudoscalarpseudoscalar type diquark pairs respectively. The numerical results indicate that the scalar mesons f0(980) and a0(980) may have two possible diquarkantidiquark substructures. PACS numbers: 12.38.Lg; 13.25.Jx; 14.40.Cs

QCD Laplace sum-rules for light-quark I = 0, 1 scalar currents are used to investigate candidates for the lightest q ¯ q scalar mesons. The theoretical predictions for the sum-rules include instanton contributions which split the degeneracy between the I = 0 and I = 1 channels. The self-consistency of the theoretical predictions is verified through a Hölder inequality analysis, confirming the e...

In this article, we take the vector charmonium-like state Y (4660) as a ψ′f0(980) bound state (irrespective of the hadro-charmonium and the molecular state) tentatively, study its mass using the QCD sum rules, the numerical value MY = 4.71 ± 0.26GeV is consistent with the experimental data. Considering the SU(3) symmetry of the light flavor quarks and the heavy quark symmetry, we also study the...
متن کاملHölder Inequalities and Isospin Splitting of the Quark Scalar Mesons
A Hölder inequality analysis of the QCD Laplace sum-rule which probes the non-strange (nn̄) components of the I = {0, 1} (light-quark) scalar mesons supports the methodological consistency of an effective continuum contribution from instanton effects. This revised formulation enhances the magnitude of the instanton contributions which split the degeneracy between the I = 0 and I = 1 channels. De...
متن کاملSearch for the scalar a0 and f0 mesons in the φ radiative decays.
Search for the scalar a 0 and f 0 mesons in the φ radiative decays. Abstract The potentialities of the production of the a 0 and f 0 mesons in the φ radiative decays are considered based on a new two-channel analysis of the ππ scattering in a energy region near 1 GeV. We predict BR(φ → γf 0 (980)) ∼ 10 −5 − 10 −4 that is a great value for the decay forbidden by the Okubo-Zweig-Iizuka rule. We d...
