GLUON CONDENSATE AND MASSES OF C-QUARKS AND B-QUARKS FROM AN ANALYSISOF THE J PSI-FAMILIES AND GAMMA-FAMILIES/

It is shown that the model used by Shifman et al. [Nucl. Phys. B, 1979 , vol. 147, p. 385] to describe the experimental function R(c)(s) in t he form of the sum of delta functions and a plateau contradicts the Wi lson operator product expansion (OPE) in terms that are due to a gluon condensate. A QCD model with an infinite number of vector mesons sati sfies the requirements of the OPE for masses and electronic widths of resonances close to the experimental values. The region of allowable v alues of the c- and b-quark masses and the gluon condensate that are c ompatible with OPE is obtained.
