Web11 de dez. de 2015 · That’s what the Hierarchy Problem is, and that problem is by many measures the greatest unsolved problem in physics. We don't know the answer, but we're not completely in the dark on this. Web24 de jan. de 2024 · Although the SM features many numerical hierarchies, the majority of them are technically-natural ones that could be explained by physics at inaccessibly high energies. The most urgent problems are the hierarchies that aren’t technically natural, like the CC problem and the electroweak hierarchy problem.

Web27 de mai. de 2015 · The axion has appeared in theoretical equations since 1977 and is deemed likely to exist. Yet no one, until now, noticed that axions could be what the trio calls “relaxions,” solving the hierarchy problem by “relaxing” the value of the Higgs mass. “It’s a very, very clever idea,” said Raman Sundrum, a theoretical particle ... 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
• 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…
In theoretical physics, the hierarchy problem is the problem concerning the large discrepancy between aspects of the weak force and gravity. There is no scientific consensus on why, for example, the weak force is 10 times stronger than gravity. Ver mais A hierarchy problem occurs when the fundamental value of some physical parameter, such as a coupling constant or a mass, in some Lagrangian is vastly different from its effective value, which is the value that gets … Ver mais The Higgs mass In particle physics, the most important hierarchy problem is the question that asks why the weak force is 10 times as strong as Ver mais Suppose a physics model requires four parameters which allow it to produce a very high-quality working model, generating predictions of some aspect of our physical universe.
