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.

The Higgs mass mystery: Why is everything so light?

WebHowever, the question that requires physics beyond the SM at the TeV, is the so called gauge hierarchy problem. One way to state it is simply by asking: why is the weak scale ( 100 GeV) so much smaller than the Planck scale (~ 10 19 GeV)? The weak scale is given by the VEV of the Higgs, v 246 GeV, the only dimensionfull parameter in the SM. WebCosmological fine tuning, supersymmetry and the gauge hierarchy problem . × Close Log In.
