PHYSICS OF ELEMENTARY PARTICLES AND FIELDS: Fermion Corrections to Mass of Scalar Glueball in QCD Sum Rule
Abstract
Contributions of fermions to the mass of the scalar glueball 0++ are calculated at two-loop level in the framework of QCD sum rules. It slightly changes the coefficients in the operator product expansion (OPE) and shifts the mass of glueball to 1.72 ± 0.07 GeV.
