Web21 de set. de 2024 · We review and discuss recent work exploring the implications of the Higgs field for early universe cosmology, and vice versa. Depending on the model under consideration, the Higgs may be one of a few scalar fields determining the evolution and fate of the Universe, or the Higgs field may be connected to a rich sector of scalar … Web9 de mar. de 2016 · Starting from a model with two complex Higgs doublets (as e.g. in the MSSM) we arrive at 5 physical Higgs bosons (instead of 1 as in the Standard Model), 2 of which are charged and 3 are neutral. One of the neutral Higgs bosons is a pseudoscalar (CP-odd), the other two are "proper" scalars (CP-even). In Drees' "Sparticles", it says
Web25 de abr. de 2024 · The usual units for the strength of the Higgs field are gigaelectronvolts. The vacuum expectation value of the field (at every point!) is 246 GeV. Particle physicists generally use natural units where $\hbar$ and $c$ are $1$; mass, energy, and momentum are measured in GeV; and length and time are measured in GeV $^ {-1}$. In the Standard Model, the Higgs field is a scalar tachyonic field – scalar meaning it does not transform under Lorentz transformations, and tachyonic meaning the field (but not the particle) has imaginary mass, and in certain configurations must undergo symmetry breaking. It consists of four components: Two neutral ones and two charged component fields. Both of the charged components and one …

WebRepresenting the Higgs scalar in terms of four real field components, the Brout-Englert-Higgs mechanism is found to remove three of them, leaving only one neutral, physical Higgs particle. SU (2) × U (1) is broken into a diagonal subgroup U (1). Three of the four gauge fields gain a mass.
