摘要
The transverse part of the two-point function of the 1^(-/+) vector gluonic current is calculated by including the perturbative contributions and the non-perturbative ones resulted from condensates of dimensions up to six.In a usual"resonance plus continuum " model of the spectral function,the quantum chromodynamics sum rules for the 1^(-/+) vector odd-glueball are derived,and the 1^(-/+) mass of that glueball is determined to be 1.87 GeV.
