Maybe we really don't need supersymmetry.... Webb1 nov. 2024 · Understanding naturalness as the imposition that fine-tuning problems have to vanish, for instance, due to the existence of new particles, new models as those based in supersymmetry were built. In order to palliate the fine-tuning problem the Higgs sector of the standard model seems to suffer, new physics should have appeared already in the …

WebbNaturalness has for many years been a guiding principle in the search for physics beyond the Standard Model, particularly for understanding the physics of electroweak symmetry breaking. However, the discovery of the Higgs particle at 125 GeV, accompanied by the exclusion of many types of new physics expected in natural models, has called the … Webbnaturalness has existed in the physics literature for quite some time; indeed, it is clearly stated in some of the earliest discussions of the concept in the late 1970s. 3 However, over time a variety of technical conditions for ensuring naturalness have developed and the under-standing of naturalness has shifted in a direction that obscures its

From the "flatness problem" in Cosmology to the "strong CP problem" and "hierarchy problem" in the Model … WebbNaturalness, as a guiding principle for effective field theories (EFTs), requires that there be no sensitive correlations between phenomena at low- and high-energy scales. This essay considers four reasons to adopt this principle: (i) natural EFTs exhibit modest empirical success; (ii) unnatural EFTs are improbable; (iii) naturalness underwrites what Williams …
