摘要 | The effects of the leading quark mass corrections to the QCD sum rules for the 0++ scalar glueball are investigated. In order to include the information from the confinement region of QCD, the leading quark mass correction to the polarization function at Q2 = 0 for a renormalized group-invariant current with the quantum numbers J(PT) = O++ are studied by means of the QCD low-energy theorem. For the construction of the corresponding spectral function, we use a 'finite-width resonance plus continuum' model in which the dynamical corrections due to the non-vanishing meson masses are taken into account. Two types of the QCD sum rules, namely the Gauss-Weierstrass finite-energy sum rules and the Laplace transform sum rule, are used to investigate the properties of the lowest O++ scalar glueball. The effects of the non-vanishing quark masses turn out to be not negligible for the determination of the glueball width; the intermediate value of the glueball mass is further confirmed by the leading quark mass correction. |
