... It is common in the realm of the elementary particle physics to redefine units so that speed of light and Plank’s constant become equal to one: c=1 and ℏ =1. This imposes two constraints on the three kinematical units and, therefore, leaves us a free choice for one of the three kinematical units. Th ...

Technicolor (physics)

Technicolor theories are models of physics beyond the standard model that address electroweak gauge symmetry breaking, the mechanism through which W and Z bosons acquire masses. Early technicolor theories were modelled on quantum chromodynamics (QCD), the ""color"" theory of the strong nuclear force, which inspired their name.Instead of introducing elementary Higgs bosons to explain observed phenomena, technicolor models hide electroweak symmetry and generate masses for the W and Z bosons through the dynamics of new gauge interactions. Although asymptotically free at very high energies, these interactions must become strong and confining (and hence unobservable) at lower energies that have been experimentally probed. This dynamical approach is natural and avoids issues of Quantum triviality and the hierarchy problem of the Standard Model.In order to produce quark and lepton masses, technicolor has to be ""extended"" by additional gauge interactions. Particularly when modelled on QCD, extended technicolor is challenged by experimental constraints on flavor-changing neutral current and precision electroweak measurements. It is not known what is the extended technicolor dynamics.Much technicolor research focuses on exploring strongly interacting gauge theories other than QCD, in order to evade some of these challenges. A particularly active framework is ""walking"" technicolor, which exhibits nearly conformal behavior caused by an infrared fixed point with strength just above that necessary for spontaneous chiral symmetry breaking. Whether walking can occur and lead to agreement with precision electroweak measurements is being studied through non-perturbative lattice simulations.Experiments at the Large Hadron Collider are expected to discover the mechanism responsible for electroweak symmetry breaking, and will be critical for determining whether the technicolor framework provides the correct description of nature. In 2012 these experiments declared the discovery of a Higgs-like boson with mass approximately 7002125000000000000♠125 GeV/c2; such a particle is not generically predicted by technicolor models, but can be accommodated by them.
