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

Successful HI requires an O(2e) deviation from central values toward either larger Higgs boson mass or smaller top quark mass. Gauge depende

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
