It is based upon a nontrivial fixed point of the corresponding renormalization group (RG) flow such that the running coupling constants approach this fixed point in the ultraviolet (UV) limit. This suffices to avoid divergences in physical observables. Moreover, it has predictive power: Generically an arbitrary starting configuration of coupling constants given at some RG scale does not run into the fixed point for increasing scale, but a subset of configurations might have the desired UV properties. For this reason it is possible that \u2014 assuming a particular set of couplings has been measured in an experiment \u2014 the requirement of asymptotic safety fixes all remaining couplings in such a way that the UV fixed point is approached. (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4Asymptotic safety, if realized in Nature, has far reaching consequences in all areas where quantum effects of gravity are to be expected. Their exploration, however, is still in its infancy. By now there are some phenomenological studies concerning the implications of asymptotic safety in particle physics, astrophysics and cosmology, for instance.Table of ContentsAsymptotic safety and the parameters of the Standard Model[edit]The mass of the Higgs boson[edit]The fine structure constant[edit]Asymptotic safety in astrophysics and cosmology[edit]See also[edit]References[edit]Asymptotic safety and the parameters of the Standard Model[edit]The mass of the Higgs boson[edit]The Standard Model in combination with asymptotic safety might be valid up to arbitrarily high energies. Based on the assumption that this is indeed correct it is possible to make a statement about the Higgs boson mass.[1] The first concrete results were obtained by Shaposhnikov and Wetterich in 2010.[2]Depending on the sign of the gravity induced anomalous dimension (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4A\u03bb{displaystyle A_{lambda }} there are two possibilities: For A\u03bb"},{"@context":"http:\/\/schema.org\/","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"https:\/\/wiki.edu.vn\/en\/wiki24\/#breadcrumbitem","name":"Enzyklop\u00e4die"}},{"@type":"ListItem","position":2,"item":{"@id":"https:\/\/wiki.edu.vn\/en\/wiki24\/physics-applications-of-asymptotically-safe-gravity\/#breadcrumbitem","name":"Physics applications of asymptotically safe gravity"}}]}]
