Physical Masses and the Vacuum Expectation Value of the Higgs Field
By using the Ward-Takahashi identities in the Landau gauge, we derive exact relations between particle masses and the vacuum expectation value of the Higgs field in the Abelian gauge field theory with a Higgs meson. PACS numbers : 03.70.+k; 11.15-q Despite the pioneering work of ’t Hooft and Veltman on the renormalizability of gauge field theories with a spontaneously broken vacuum symmetry, a ...

متن کاملCosmological 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...
متن کاملThe Effect of Time Variation in the Higgs Vacuum Expectation Value on the Cosmic Microwave Background
The possibility that the fundamental constants of nature are not, in fact, constant, but might vary with time has long been an object of speculation by physicists [1]. The fundamental constants which have received the greatest attention in this regard are the coupling constants which determine the interaction strengths of the fundamental forces: the gravitational constant G, the fine-structure ...
متن کاملGaugino 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...
