The Hierarchy Problem – Of Particular Significance

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? 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. d5 they\\u0027d

For example: Supersymmetry (SUSY). By the way, QCD doesn't have the hierarchy problem (apart from the strong CP-problem...). d5 they\u0027ll

"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.
