Web3 de out. de 2024 · Nevertheless, the hierarchy between the weak and the Planck scales remains unexplained. We argue that this hierarchy can be generated by a non-perturbative effect relating the low energy and the Planck-scale physics. The effect is manifested in the existence of an instanton configuration contributing to the vacuum expectation value of … WebThe RS1 model attempts to address the hierarchy problem. The warping of the extra dimension is analogous to the warping of spacetime in the vicinity of a massive object, such as a black hole . This warping, or red-shifting, generates a large ratio of energy scales, so that the natural energy scale at one end of the extra dimension is much larger than at the …

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.

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 ...
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).
