WebThe hierarchy problem is roughly: A scalar particle such as the Higgs receives quadratically divergent corrections, that have to cancel out delicately with the bare mass to give the observed Higgs mass. I have a couple of related questions about that: Why is this a problem, isn't this just ordinary renormalization?

Physics - Naturalness Hits a Snag with Higgs

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. 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.

If supersymmetry is not found at the LHC, we’re going to have to do a proper re-think about our philosophy of renormalization.

Web22 de fev. de 2024 · This is a particular manifestation of the Hierarchy Problem. 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. Web10 de fev. de 2014 · The hierarchy problem concerns a very small number. The smallness of the physical observable can be “naturally” preserved under its quantum correction provided that some symmetry is enhanced in the action of …

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...). 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 measured in an experiment. This happens because the effective value is related to … Ver mais In theoretical physics, the hierarchy problem is the problem concerning the large discrepancy between aspects of the weak force and gravity.
