WebHá 1 dia · Exploring Mirror Twin Higgs Cosmology with Present and Future Weak Lensing Surveys. 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 … 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 …

WebA new solution to the hierarchy problem involving extra spatial dimensions was proposed in Ref. [3]. In this setup, there are 3 + n spatial dimensions, with n compact dimensions of a typical compactification radius R. All matter and gauge fields are confined to a four-dimensional slice, a brane.

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?
