The 2^(++) Three-Gluon Tensor Glueball in Quantum Chromodynamics Sum Rules

The three-gluon tensor current of quantum numbers Jpc=2^(++) is constructed.The corresponding two-point function is calculated by including not only the perturbative contribution but also the non-perturbative ones resulting from condensates of dimensions up to six.In a usual“resonance plus continuum”model of the spectral function of the current,the quantum chromodynamics sum rules for the 2^(++) three-gluon tensor glueball are deduced,and the mass of that glueball is determined to be 2.0 GeV approximately.
