If the Higgs had turned out (as was possible) not to exist, fundamental physics would have been turned in ...

Certainly, if Λ is too small, our effective lagrangian becomes unreliable. Instead, we should work on the underlying theory. We should also mention that the mechanism for rel ...

... Likewise any baryon consists of three quarks and any antibaryon of three antiquarks, e.g. two up quarks and one down quark make a proton. If we look closely at this model, we see that different quarks in one particle can have the same quantum numbers like the three strange quarks in the Ω− hadron. B ...

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.
