Web26 de dez. de 2024 · That is, inflation takes place below the cutoff scale. It is an implicit assumption of the Higgs inflation that such an extension does not affect the result qualitatively, that is, the Wilson coefficients of the higher order terms are sufficiently smaller than 1/ξ1𝜉1/\xi1 / italic_ξ. Web2 de ago. de 2024 · The latter solves the strong CP problem and accounts for the cold dark matter in the Universe. The inflaton is comprised by a mixture of σ and the SM Higgs, and reheating of the Universe after inflation proceeds via the Higgs portal. Baryogenesis occurs via thermal leptogenesis.

WebThe Brout–Englert–Higgs–Guralnik–Hagen–Kibble boson, simply called the Higgs boson here, seems to be a fundamental scalar field. So, we can imagine that the QCD axion and an inflation may be fundamental fields also. dating chevron beads
