We predict … WebThe RS1 model attempts to address the hierarchy problem. The warping of the extra dimension is analogous to the warping of spacetime in the vicinity of a massive object, such as a black hole . This warping, or red-shifting, generates a large ratio of energy scales, so that the natural energy scale at one end of the extra dimension is much larger than at the …
• Hierarchy problem: Why is gravity such a weak force? It becomes strong for particles only at the Planck scale, around 10 GeV, much above the electroweak scale (100 GeV, the energy scale dominating physics at low energies). Why are these scales so different from each other? What prevents quantities at the electroweak scale, such as the Higgs boson mass, from getting quantum corrections on the order of the Planck scale? Is the solution supersymmetry, extra dimensions, o… Web19 de ago. de 2011 · The issue, now called the hierarchy problem, has to do with the size of the non-zero Higgs field, which in turn determines the mass of the W and Z particles. …
