A Dimensional Transmutation

    Here there is some explanation about dimensional transmutation that answered some of the questions I had about it.Those explanations are all I understand about the subject. But I still have some questions.

    1) Is it correct to say that dimensional transmutation means you can replace the coupling constant in the Lagrangian with the energy scale using the RG flow equation? i.e. Does dimensional transmutation mean doing ## L[g]\to L[\Lambda] ##?

    2) How is it that we still can do perturbation theory using the coupling constant in the weakly coupled (high energy) regime of QCD? How is it that dimensional transmutation doesn't affect that regime?

    Thanks

    Thanks for the thread! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post? The more details the better.
