Web14 de mai. de 2024 · I am struggling to understand the argument for why the introduction of a stop in SUSY can solve the hierarchy problem. The quadratic divergence from the top loop in the higgs mass calculation gives a contribution of δ m h 2 = − y f 2 16 π 2 [ 2 Λ 2 + …] If we introduce a scalar S, there should be two additional diagrams to consider: and WebAccording to quantum field theory, the mass of the Higgs boson must be rather light for the electroweak theory to work. However, the loop corrections to the mass are naturally much greater; this is known as the hierarchy problem.
Web11 de dez. de 2015 · Although this could have been a plausible solution in principle, the recent discovery of what appears to be a fundamental, spin-0 scalar at the right energy to be the Higgs seems to invalidate... Web28 de jan. de 2024 · The problem arises solely by investigating the tree-level Higgs potential. But there is also a hierarchy problem which has to do with loops, i.e. higher orders in perturbation theory. The main observation is that our bare Higgs mass $m$ (the parameter in the Lagrangian) gets modified if we move beyond the tree-level.
WebHowever, the question that requires physics beyond the SM at the TeV, is the so called gauge hierarchy problem. One way to state it is simply by asking: why is the weak scale ( 100 GeV) so much smaller than the Planck scale (~ 10 19 GeV)? The weak scale is given by the VEV of the Higgs, v 246 GeV, the only dimensionfull parameter in the SM.
