The discovery of the Higgs physics together with the excellent performance of the LHC allow to make precision tests of Brout-Englert-Higgs Physics.

At this level, it becomes important to fully understand the theory behind this physics. As was already pointed out more than 35 years ago, there is a paradox in the standard model: The elementary fields should not be the particles we observe, as they are unphysical, since they are gauge-dependent. Nonetheless, it appears that we see them. The resolution of this paradox shows that the standard model is a very special theory, where the description in both languages is (almost) identical.

However, this can drastically change beyond the standard model, even altering usual predictions of particle spectra. It could also subtly alter precision measurements within the standard model. This yields testable predictions, which can (mostly) be derived with little more effort than in standard phenomenology.

After sketching the underlying theory ideas, these predictions for experimental signatures will be presented.
