WebMar 9, 2024 · An equivalent form of the Einstein-Hilbert Lagrangian with a non-minimally coupled scalar field corresponding to the function [[EQUATION]] is found. Due to the geometrical feature of the Weyl field, it turns out that the symmetry breaking induces a non-minimal coupling, which cannot be expected in the standard f(R) theories. WebWe show how the fields and particles of the standard model can be naturally realized in noncommutative gauge theory. Starting with a Yang-Mills matrix model in more than 4 dimensions, a gauge theory on a Moyal-Weyl sp… kpmg security jobs
Weyl scaling invariant R 2 gravity for inflation and dark matter
Web(Higgs-like), with couplings allowed by Weyl gauge symmetry, after its spontaneous breaking one obtains in addition, at low scales, a Higgs potential with spontaneous electroweak symmetry breaking. This is induced by the non-minimal coupling ξ1φ2 1 R˜ to Weyl geometry, with Higgs mass ∝ξ1/ξ0 (ξ0 is the coefficient of the R˜2 term). In WebJul 24, 2003 · Symmetry and Symmetry Breaking. First published Thu Jul 24, 2003; substantive revision Thu Dec 14, 2024. Symmetry considerations dominate modern fundamental physics, both in quantum theory and in relativity. Philosophers are now beginning to devote increasing attention to such issues as the significance of gauge … WebMar 15, 2024 · The order parameter of this symmetry breaking is the matrix e^\mu _a, which plays the role of the tetrad of the emergent 3+1 gravity. The Minkowski vacuum becomes degenerate with respect to each of the two SO (1, 3) rotations, but remains invariant under the combined Lorentz transformation L_ {J}. manus-bond 50a-hv
