Hierarchy problem in physics
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. Suppose we find through experiments that the parameters have values: 1.2, … Ver mais • Naturalness • CP violation • Quantum triviality • Weak gravity conjecture Ver mais Web10 de jul. de 2024 · This work is licensed by OpenStax University Physics under a Creative Commons Attribution License (by 4.0).

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 ( … Web6 de fev. de 2024 · Alternative forms of the solutions to the quantum field equations and their implications for physical theory are considered.

Web24 de mai. de 2024 · This is what we call the hierarchy problem. It implies that the electroweak vacuum expectation value (vev) v ( {=}246) GeV is not protected either ( m_h \sim \lambda v, where \lambda is the quartic coupling). Thus the entire SM is plagued by the hierarchy problem. Do we then have to accept a miraculous cancellation of one part in … 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 ...

WebIn theoretical physics, fine-tuning is the process in which parameters of a model must be adjusted very precisely in order to fit with certain observations. This had led to the discovery that the fundamental constants and quantities fall into such an extraordinarily precise range that if it did not, the origin and evolution of conscious agents in the universe would not be …
