|
For moments of leptoproduction structure functions we show that all
dependence on the renormalization and factorization scales disappears
provided that all the ultraviolet logarithms involving the physical
energy scale Q are completely resummed.
The approach is closely related to Grunberg's method of
Effective Charges.
A direct and simple method for extracting Λ―MS
from experimental data is advocated.
