Higgs is like a toilet. It hides all the messy details we would rather not speak of. The Higgs field, as elegant as it might be, is within the Stan- dard Model essentially an ad hoc addition. It is added to the theory to do what is required to accurately model the world of our experience. But it is not req

Strong Interactions."

ited to try to make sense of the otherwise complex inter- actions between nucleons and other particles. In response to this notion that some kind of Yang-Mills symmetry might be behind the strong interaction, Murray Gell-Mann developed an elegant symmetry scheme he labeled in a Zen-like fashion the Eight-

GAUGE DEPENDENCE AMBIGUITIES When working with a gauge theory, such as the Stan- dard Model electroweak sector, calculations typically involve spurious gauge dependence that cancels when physical ob- servable are calculated. For example, in
