Description
The naturalness principle motivated the theoretical expectation that light scalars cannot exist unless they come together with new physics that protects their lightness, such as supersymmetry. But LHC run I discovered the Higgs scalar without any sign of new physics. I review and reconsider the issue of naturalness, proposing a possible modification.
