Quantum Chromodynamics Sum Rules for the 0++ Three-Gluon Scalar Glueball

  • Department of Physics, Wuhan University, Wuhan, China
Fund Project:  Supported by the National Natural Science Foundation of China.

Abstract: The two-point function of the 0++ three-gluon scalar current is calculated in including not only the perturbative contribution but also the nonperturbative ones resulted from condensates of dimensions up to six. In a typical "resonance plus continuum" model of the spectral function of the current, the quantum chromodynamics sum rules for the 0++ three-gluon scalar glueball are deduced, and the mass of that glueball is determined to be approximately 1.45GeV.
