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. WebHowever, the Higgs has never been definitively observed (M Higgs > 114 GeV at 95% CL [2]). A Standard Model Higgs suffers from the so-called hierarchy problem. The theory …

We explore the potential of precision cosmological data to study non-minimal dark sectors by updating the cosmological constraint on the mirror twin Higgs model (MTH). The MTH model addresses the Higgs little hierarchy problem by introducing dark sector … Web17 de mai. de 2024 · The Hierarchy Problem and the Cosmological Constant Problem Revisited Higgs Inflation and a New View on the SM of Particle Physics Fred …
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?
