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. The main observation is that our bare Higgs mass $m$ (the parameter in the Lagrangian) gets modified if we move beyond the tree-level. 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.

Web1.1 The Hierarchy Problem The Hierarchy Problem tends to be the overarching name used by physicists to refer to a couple of di erent things, the rst of which is the di erence in scales between the mass of the electroweak gauge bosons/Higgs and the Planck mass. The calculation of the Higgs mass 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 …
