WebJun 30, 2024 · The electroweak hierarchy problem has been recognized as the most notorious difficulty for the high-energy physics in the past decades and often rephrased … 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. See more 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 … See more 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 gravity. Both of these forces involve constants of nature, the Fermi constant for … See more 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, … See more • Naturalness • CP violation • Quantum triviality See more

WebWeak hypercharge is the generator of the U(1) component of the electroweak gauge group, SU(2) × U(1) and its associated quantum field B mixes with the W 3 electroweak quantum field to produce the observed Z gauge boson and the photon of quantum electrodynamics.. The weak hypercharge satisfies the relation = + , where Q is the … Webto the electroweak hierarchy problem [4, 5]. A popular example of UV/IR mixing that has received increased attention recently is the Cohen-Kaplan-Nelson(CKN) bound on quantum correctionscon-tributing to the dark energy density in the universe [6].

We present a family-non-universal extension of the Standard Model where the first two families feature both quark-lepton and electroweak-flavour unification, via the SU (4) Sp (4) L Sp (4) R gauge group, whereas quark-lepton unification for the third family is realised à la Pati-Salam. Via staggered symmetry breaking steps, this ... WebJul 30, 2024 · Download PDF Abstract: It was recently proposed that the electroweak hierarchy problem is absent if the generation of the Higgs potential stems exclusively from quantum effects of heavy right-handed neutrinos which can also generate active neutrino masses via the type-I seesaw mechanism.
