Supersymmetry and the Crisis in Physics

by Joseph Lykken and Maria Spiropulu with the prologue "For decades physicists have been working on a beautiful theory that has promised to lead to a deeper understanding of the quantum world.Now they stand at a crossroads:prove it right in the next year or confront an epochal paradigm shift"

Inside the article is written: "If supersymmetry is not a true description of the world, what

might take its place? Here are three different speculative answers. All of them imply profoundly new directions for thinking about basic physics and cosmology:"

They are enumated as:

1. Multiverse

2. Extra Dimensions

3. Dimensional Transmutation

The Extra Dimensions have been refuted already and Multiverse silly so we are left with one option which is Dimensional Transmutation.

In the Search option at physicsforums. The word "Dimensional Transmutation" has zero hit. The Scientific American article has the only layman reference to it in the whole world. Now with Supersymmetry almost refuted and other candidates. The concept of "Dimensional Transmutation" would become popular.

Quoting Sci-Am intro to Dimensional Transmutation:

"Dimensional transmutation: Instead of invoking supersymmetry

to suppress virtual particle effects, a new idea is to embrace

such effects to explain where mass comes from. Consider for a

moment the proton. The proton is not an elementary particle. It is

made up of an assembly of three quarks, which have a minuscule

mass, and gluons, which have no mass at all. The proton is much

heavier than the sum total of the quarks and gluons inside of it.

Where does this mass come from? It comes from the energy fields

generated by the “strong” force that holds the proton together.

Our understanding of these fields allows us to accurately predict

the proton’s mass based on just ordinary numbers such as pi.

It’s an odd situation in particle physics. Usually we can compute

masses only by starting with other masses. For example, the

Standard Model gives us no way to predict the mass of the Higgs

boson—we have to measure it. This seems like an obvious mistake,

given how cleverly we can predict the mass of the proton.

Building on seminal work by William A. Bardeen, a physicist at

Fermilab, a few radical theorists are now suggesting that the

Higgs mass scale is generated through a similar process called

dimensional transmutation."

Physicforums members. Can you give in your own words the meaning of dimensional transmutation? I know it is related to renormalization, coupling constants, perturbations in QFT, etc. I know what they mean.. but the scientific american article falls short of saying how it is related to the Higgs bosons. I know the meaning of the Hierarchy Problem and Naturalness and how the Higgs mass should have been pulled up to the Planck Mass because of virtual particles contribution.. but how is Dimensional Transmutation related to this... is it saying the Standard Model particles didn't get the mass from the Higgs. If not.. what is the function of dimensional transmutation? Is it related to new physics in the Electroweak Sector.. and what kind of hidden physics would support the process of Dimensional Transmutation?

The following are the professional references about it.

Please dumb it down for us laymen because Dimensional Transmutation will become popular as serious alternative to Supersymmetry. Thank you!
