lid varies with 41. We find that 14„r also changes at a level comparable to its sensitivity to Mg or Ali as the gauge pa- rameter deviates from the Landau gauge (egc = 0). It is there- fore important to consider this ambiguity for model building purposes. Nevertheless, the absolute change in lid is far

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.

losely surround the negative charge, and so at a distance the physical effects of the initial negative charge are reduced. This meant, according to Landau, that the closer you get to an elec- tron, the larger its actual charge will appear. If we measure the electron charge to be some specific value at

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
