Web22 de abr. de 2024 · 1 While reading up on hierarchy problems in particle physics ( wikipedia ), I stumbled onto the statement that in the Standard Model, there is no hierarchy problem (or at least it cannot be formulated) since the Higgs mass can not be calculated. I don't understand what exactly is meant by this. Web18 de nov. de 2024 · The issue, now called the hierarchy problem, has to do with the size of the non-zero Higgs field, which in turn determines the mass of the W and Z particles. The non-zero Higgs field has a size of about 250 GeV, and that gives us the W and Z particles with masses of about 100 GeV. biometrics school lunch

WebOne could solve the hierarchy problem by introducing new degrees of freedom that enforce such a cancellation as a symmetry requirement (rather than accidentally) which would suppress the couplings of the relevant operator. For example: Supersymmetry (SUSY). By the way, QCD doesn't have the hierarchy problem (apart from the strong CP-problem...). Web7 de dez. de 2024 · Fred Jegerlehner We argue that the Standard Model (SM) in the Higgs phase does not suffer from a "hierarchy problem" and that similarly the "cosmological constant problem" resolves itself if we understand the SM as a low energy effective theory emerging from a cutoff-medium at the Planck scale.

The correction to the Higgs means that its energy scale is comparable to that of the gravitational (or Planck) scale. But if this is the case why is it so much larger than the weak scale? It is here that supersymmetry proposes a resolution.
