Web5 de mar. de 2009 · We make an estimate of the likelihood function for the Higgs vacuum expectation value by imposing anthropic constraints on the existence of atoms while allowing the other parameters of the Standard Model to also be variable. 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 …
Web28 de out. de 2024 · Vacuum expectation value renormalization in the Standard Model and beyond Vytautas Dūdėnas, Maximilian Löschner We show how the renormalization constant of the Higgs vacuum expectation value, fixed by a tadpole condition, is responsible for gauge dependences in various definitions of parameters in the -gauge. Web12 de dez. de 2011 · johne1618, As you say, the vacuum expectation value of the Higgs field is v = 246 GeV. It serves to set the scale for the other particle masses induced by the Higgs, for example m W = ½vg where g is one of the weak coupling constants. But it's not the expectation value of the Hamiltonian.
Webifies the probability of finding different values of the pa-rameters. These probabilities would emerge from string theory and the weight encodes the shape of the string landscape. Let us call this weight ρ(v,Γi,gi) where v is the Higgs vacuum expectation value, Γi are the Yukawa couplings, and gi stands for the gauge couplings and all Web13 de abr. de 2024 · Alternatively, one can employ the so-called Fleischer-Jegerlehner scheme [70] that shifts the bare vacuum expectation value by Δv ¼ −δt=m 2 H , where m H is the Higgs mass, at the cost of...
