New method for renormalon subtraction using Fourier transform
To improve accuracy in calculating QCD effects, we propose a method for renormalon subtraction in the context of the operator-product expansion. The method enables subtracting renormalons of various powers in ΛQCD efficiently and simultaneously from single-scale observables. We apply it to different...
