Webshown, a large cut-off will introduce another problem to the SM, the Hierarchy Problem [1, 5, 9, 10]. This problem is much more conceptual compared to other issues of the SM and has a deep connection to the EFT framework. Moreover, it guided the theoretical development of particle physics for the last decades and is still one of the most important Web9 de dez. de 1998 · Hierarchy problem in the shell-Universe model. Merab Gogberashvili (Tbilisi Institute of Physics) In the model where the Universe is considered as a thin shell expanding in 5-dimensional hyper-space there is a possibility to obtain one scale for particle theory corresponding to the 5-dimensional cosmological constant and Universe thickness.

• Hierarchy problem: Why is gravity such a weak force? It becomes strong for particles only at the Planck scale, around 10 GeV, much above the electroweak scale (100 GeV, the energy scale dominating physics at low energies). Why are these scales so different from each other? What prevents quantities at the electroweak scale, such as the Higgs boson mass, from getting quantum corrections on the order of the Planck scale? Is the solution supersymmetry, extra dimensions, o… Web13 de abr. de 2024 · A flood vulnerability index was constructed by coupling Geographic Information System (GIS) mapping capabilities with an Analytic Hierarchy Process (AHP) Group Decision-Making (GDM) resulting from a paired comparison matrix of expert groups to assign weights to each of the standardised criteria.

WebAnd, therefore, there are no fine-tunings or hierarchy problem in a theory describing all observed phenomena in particle physics. The only experimental evidence for the presence of another scale in Nature is gravity, meaning that any realistic description of it must have at least two widely separated essential scales, that of Fermi ( M F ∼ 100 GeV) and Planck ( …
