摘要:
The momentum subtraction scheme MOM has been empirically successful in producing small QCD corrections to physical quantities at one loop order. By explicit calculations, we show that with a suitable shift in the renormalization scale, the minimal subtraction scheme coupling constant &agr;MScoincides with typical momentum scheme coupling constants at both one and two loop order.
