Poincaré protection for a natural electroweak scale

We discuss a class of technically natural UV extensions of the Standard Model in which the electroweak scale is shielded from large radiative corrections from heavy UV physics due to an enhanced Poincaré symmetry. Such heavy sectors can be invoked to provide solutions to known shortcomings of the Standard Model, such as the strong-$CP$ problem, the absence of dark matter, and the lack of neutrino masses. We discuss the relationship to scale-invariant models.
