... So what are we to make of this? We have a theory with an infinite number of symmetries, one for each function λ(x). Previously we only encountered symmetries which act the same at all points in spacetime, for example ψ → eiα ψ for a complex scalar field. Noether’s theorem told us that these symmetr ...

... The prototype candidate was a new interaction similar to QCD (“Technicolor”) with new particles at O(few TeV). The simplest of these models would however produce deviations from the SM that are not seen, but many more complex variants exist. These models give new quarks, bosons, ‘leptoquarks’, etc. ...
