Fermion correction to the mass of the scalar glueball in QCD sum rule

Abstract
Contributions of fermions to the mass of the scalar glueball are calculated at two-loop level in the framework of QCD sum rules. It obviously changes the coefficients in the operator product expansion (OPE) and shifts the mass of glueball.
