Higgs effective field theory
Web1 de jul. de 2024 · We formulate an extension of Higgs effective field theory which contains an arbitrary number of scalar and fermion fields with arbitrary electric and chromoelectric charges. The BSM Higgs sector is described by using the nonlinear sigma model in a manner consistent with the spontaneous electroweak symmetry breaking. Web14 de mar. de 2024 · We analyze the electroweak interactions in the framework of the Higgs effective field theory using the available Higgs and electroweak diboson production results from LHC run 2 as well as the electroweak precision data. Assuming universality of the weak current, our study considers 25 possible anomalous couplings.

We discuss vacuum stability and … Web7 de jan. de 2024 · Higgs-portal effective field theories are widely used as benchmarks in order to interpret collider and astroparticle searches for dark matter (DM) particles. To assess the validity of these effective models, it is important to confront them to concrete realizations that are complete in the ultraviolet regime.
Web20 de mai. de 2015 · For the SM effective potential (usually calculated in Landau gauge) we have the Higgs field and the Goldstone fields, with: m H ( ϕ c) = 3 λ ϕ c 2 − m 2 m G ( ϕ c) = λ ϕ c 2 − m 2 At the Higgs VEV m H ( v) = 2 m 2 and m G ( v) = 0. Where m and λ are the renormalized parameters of the tree level Higgs potential. Effective field theories typically work best when there is a large separation between length scale of interest and the length scale of the underlying dynamics. Effective field theories have found use in particle physics, statistical mechanics, condensed matter physics, general relativity, and hydrodynamics.
