Higgs mass hierarchy problem
This problem, called the cosmological constant problem, is a hierarchy problem very similar to that of the Higgs boson mass problem, since the cosmological constant is also very sensitive to quantum corrections, but it is complicated by the necessary involvement of general relativity in the problem. Ver mais 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 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 … Ver mais • Naturalness • CP violation • Quantum triviality Ver mais A hierarchy problem occurs when the fundamental value of some physical parameter, such as a coupling constant or a mass, in some 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 gravity. Both of these forces involve constants of nature, the Fermi constant for … Ver mais Web26 de mar. de 2024 · The hierarchy problem has its origin in interpreting the mass of the recently discovered Higgs boson. To get down to what the problem is about, we have to first think about mass more generally. If you only know one equation from physics, it’s probably E=mc2. This says that energy and mass are basically the same thing, just in …

Web28 de jan. de 2024 · The problem arises solely by investigating the tree-level Higgs potential. But there is also a hierarchy problem which has to do with loops, i.e. higher orders in perturbation theory.
