After 3 hours of google search. I found out scale symmetry is related to dimensional transmutation that can replace the supersymmetric particles that can solve the Hierarchy Problem of the Higgs (this is the hottest thing in LHC and physics right now). Scale symmetry is the key to understand all this. There is almost zero hit about scale symmetry in Physicsforums so let me share the details and the questions. The following article is directly connected to the Sci-Am article on Hierarchy problem and dimensional transmutation https://www.quantamagazine.org/20140818-at-multiverse-impasse-a-new-theory-of-scale/ quoting... "This little-explored idea, known as scale symmetry, constitutes a radical departure from long-standing assumptions about how elementary particles acquire their properties. But it has recently emerged as a common theme of numerous talks and papers by respected particle physicists. With their field stuck at a nasty impasse, the researchers have returned to the master equations that describe the known particles and their interactions, and are asking: What happens when you erase the terms in the equations having to do with mass and length? Nature, at the deepest level, may not differentiate between scales. With scale symmetry, physicists start with a basic equation that sets forth a massless collection of particles, each a unique confluence of characteristics such as whether it is matter or antimatter and has positive or negative electric charge. As these particles attract and repel one another and the effects of their interactions cascade like dominoes through the calculations, scale symmetry “breaks,” and masses and lengths spontaneously arise. ..... (continue quoting) The scale symmetry approach traces back to 1995, when http://theory.fnal.gov/people/bardeen/wbardeen.html?__hstc=13887208.fd3fbbf9f7855dfcee679370f812aa59.1472103875706.1472103875707.1472288820401.3&__hssc=13887208.2.1472288820401&__hsfp=559246593 [Broken], a theoretical physicist at Fermi National Accelerator Laboratory in Batavia, Ill., showed that the mass of the Higgs boson and the other Standard Model particles could be calculated as consequences of spontaneous scale-symmetry breaking." What do you make of it? If scale symmetry and dimensional transmutation is unlikely.. then the solution to the Hiearchy Problem with missing supersymmetric particles may be Multiverse which is extremely excess baggage.. so scale symmetry may be the Occam Razor's.
