Higgs Dynamics during Inflation
نویسنده
چکیده
With the discovery of the Higgs boson, and recent measurements from the BICEP2 collaboration indicating a tensor-to-scalar ratio of r = 0.20 −0.05[1], particle physics is now in an interesting position. The most precise measurements of the Higgs boson and top quark masses appear to show that the Electroweak vacuum is unstable under the fluctuations produced by inflation at the energy scale the BICEP results imply[2][3]. In this report we review the physics of electroweak vacuum stability, with particular emphasis on methods for solving the Fokker-Planck equation. We also present numerical results for a method of solving the Fokker-Planck eigenvalue problem, by means of a harmonic oscillator basis.

Spacetime Curvature and Higgs Stability after Inflation.
We investigate the dynamics of the Higgs field at the end of inflation in the minimal scenario consisting of an inflaton field coupled to the standard model only through the nonminimal gravitational coupling ξ of the Higgs field. Such a coupling is required by renormalization of the standard model in curved space, and in the current scenario also by vacuum stability during high-scale inflation....

متن کاملPrethermalisation and the Build-up of the Higgs Effect
Tracking the transmutation of the angular component of a complex Higgs field into the longitudinal polarisation state of the gauge field during the termination of inflation in hybrid models might reveal interesting details of the real time Higgs effect and of the electroweak dynamics . The excitation rate of the different polarisation states might be different as well as the thermal relaxation ...
متن کامل0 Electroweak preheating on a lattice
In many inflationary models, a large amount of energy is transferred rapidly to the long-wavelength matter fields during a period of preheating after inflation. We study how this changes the dynamics of the electroweak phase transition if inflation ends at the electroweak scale. We simulate a classical SU(2)×U(1)+Higgs model with initial conditions in which the energy is concentrated in the lon...

We propose an alternative implementation of the curvaton mechanism for generating the curvature perturbations which does not rely on a late decaying scalar decoupled from inflation dynamics. In our mechanism the supersymmetric Higgs scalars are coupled to the inflaton in a hybrid inflation model, and this allows the conversion of the isocurvature perturbations of the Higgs fields to the observe...
