# Conformal symmetry and the Standard Model

@article{Meissner2007ConformalSA, title={Conformal symmetry and the Standard Model}, author={Krzysztof A. Meissner and Hermann Nicolai}, journal={Physics Letters B}, year={2007}, volume={648}, pages={312-317} }

We re-examine the question of radiative symmetry breaking in the Standard Model in the presence of right-chiral neutrinos and a minimally enlarged scalar sector. We demonstrate that, with these extra ingredients, the hypothesis of classically unbroken conformal symmetry, besides naturally introducing and stabilizing a hierarchy, is compatible with all available data; in particular, there exists a set of parameters for which the model may remain viable even up to the Planck scale. The decay… Expand
