Higgs vacuum expectation value
Webv is the vacuum expectation value of the Higgs field, v = (√ 2GF)−1/2 ≈ 246 GeV, fixed by the Fermi coupling GF,which is determined precisely from muon decay measurements [24]. Since λ is presently unknown, the value of the SM Higgs boson mass mH cannot be predicted. However, besides the upper bound on the Higgs boson mass from ... WebMotivated by recent results from Higgs searches at the Large Hadron Collider, we consider possibilities to enhance the diphoton decay width of the Higgs boson over the Standard Model expectation, without modifying either its production rate or the partial widths in the WW and ZZ channels.

Web8 de mai. de 2024 · During inflation, scalar fields, including the Higgs boson, may acquire a nonzero vacuum expectation value, which must later relax to the equilibrium value during reheating. WebIn conventional spontaneous gauge symmetry breaking, there exists an unstable Higgs particle in the theory, which drives the vacuum to a symmetry-broken phase (i.e, electroweak interactions.) In dynamical gauge symmetry breaking, however, no unstable Higgs particle operates in the theory, but the bound states of the system itself provide …
