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.

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? Web1 de jul. de 2024 · Hierarchy problem The observed mass of the Higgs boson is 125 GeV, yet quantum corrections from interactions with other Standard Model particles should cause it to be 17 orders of magnitude higher at the Planck mass – a conundrum called the electroweak hierarchy problem.

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

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.
