Increasingly strong indications from the LHC that the Standard Model
violates the naturalness principle raise several possibilities: 1)
failure of naturalness is a genuinely problematic feature of the
Standard Model that we should seek to correct in the search for deeper
theories, 2) failure of naturalness is problematic, but a contingent
fact of nature that we must simply accept, 3) failure...

20. A String Landscape Perspective on Naturalness

It is an old idea that we may live in a multiverse. The fundamental parameters we observe in our local universe are then, at least to some extent, accidental. More recently, technical progress in superstring theory, which is arguably the leading candidate for a theory of quantum gravity, has given strong support to this idea. Concretely, the crucial progress came with the discovery of a very...

34. Matter in a Multi-Component Universe, Naturalness and the Quest for a Fundamental Theory

Heinrich Paes (University of Alabama)

Finetuning describes unlikely coincidences on an effective level of description which are expected to be explained in a more fundamental theory. In this talk a fresh view on the topic of Naturalness and Finetuning is presented which is based on a “holistic" concept for the most fundamental layer of reality. We start with recent research on the abundances of leptons, baryons and dark matter in...
