Vacuum expectation value renormalization in the standard model and beyond

نویسندگان

چکیده

We show how the renormalization constant of Higgs vacuum expectation value, fixed by a tadpole condition, is responsible for gauge dependences in various definitions parameters $R_{\xi}$-gauge. Then we relationship this to Fleischer-Jegerlehner (FJ) scheme, which used avoid these dependences. In way, also present viewpoint on FJ-scheme complementary ones already existing literature. Additionally, compare and discuss different approaches tadpoles identifying similarities relations between them. The background field discussed.

Gaugino Condensation and the Vacuum Expectation Value of the Dilaton

The mechanism of gaugino condensation has emerged as a prime candidate for supersymmetry breakdown in low energy effective supergravity (string) models. One of the open questions in this approach concerns the size of the gauge coupling constant which is dynamically fixed through the vev of the dilaton. We argue that a nontrivial gauge kinetic function f(S) could solve the potential problem of a...

Cosmological Evolution of the Higgs Boson’s Vacuum Expectation Value

We point out that the expansion of the universe leads to a cosmological time evolution of the vacuum expectation of the Higgs boson. Within the standard model of particle physics, the cosmological time evolution of the vacuum expectation of the Higgs leads to a cosmological time evolution of the masses of the fermions and of the electroweak gauge bosons while the scale of Quantum Chromodynamics...
