WebPossibilities that theorists envisage to tackle the Hierarchy Problem: 1) Supersymmetry: Protecting the Higgs mass by a symmetry 2) Composite Higgs: The Higgs is not … 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.

WebOne could solve the hierarchy problem by introducing new degrees of freedom that enforce such a cancellation as a symmetry requirement (rather than accidentally) which would suppress the couplings of the relevant operator. For example: Supersymmetry (SUSY). By the way, QCD doesn't have the hierarchy problem (apart from the strong CP-problem...). WebThis interaction is asymptotically free at very high energies and becomes strong and confining as the energy decreases to the electroweak scale of 246 GeV. These strong forces spontaneously break the massless fermions' chiral symmetries, some of which are weakly gauged as part of the Standard Model. dicks sports store leominster dicks sports store lexington

"WebIn this paper we consider a new variation of the little Higgs mechanism for solving the little hierarchy problem. Because the heavy top partner in this model is not colored but transforms under a new non-Abelian gauge group, we will call it the top quirk. The model is ﬁve dimensional; the extra dimension has a radius R and is orbifolded by S1 ... " - Higgs hierarchy problem
