Part 2 %XWe describe a simple momentum-space method of evaluating Wilson coefficients of gluon operators in an operator product expansion (OPE). This extends an earlier configuration-space method suitable for calculating the coefficients for light quarks. The method is illustrated by calculating the coefficients of the Lorentz scalar gluon operator of dimension four appearing in different two-point functions. %0Journal Article %N;Journal ID: CODEN: NUPBB %1 %CNetherlands %Rhttps://doi.org/ Journal ID: CODEN: NUPBB HEDB %GEnglish
