“Standard” Higgs Boson mass predicted via M-theory
This article in Nature talks about the surprise many particle physicists have regarding the 125GeV mass that seems likely for the Higgs boson. This “realistic” (as opposed to “relativistic” mass of the Higgs makes it a “standard” HIggs, rather than the “composite” (standard + relativistic) Higgs that many were expecting. The author offers the explanation that a 125 GeV “standard” Higgs can be predicted from a form of “compactified” M- theory, where the dimensions higher than 4 are left folded in on themselves (‘subspace’ Trekkies?). The best part is that for the first time, M-theory – which was thought to be an almost metaphysical concept, with no manifestation in the physical world – more “math trick” more than science – results in predictions of new particles that the LHC should be able to detect.
If confirmed, this will open a new chapter in the evolution of particle physics, and open the book on M-theory, not as a cool theoretical construct, but as a tool to drill deeper into our understanding of the universe.
