Abstract:
We discuss the specificity of charge renormalization in Yang–Mills theory.
We show that the values of the running coupling constant in dimensional
regularization and in momentum truncation coincide. Dimensional transmutation
is interpreted as replacing the dimensionless coupling constant with a
dimensional invariant of the renormalization group equation.
Keywords:
dimensional transmutation, renormalization group equations, dimensional regularization, momentum truncation.
