Higgs inflation at the critical point
نویسندگان
چکیده
Higgs inflation can occur if the Standard Model (SM) is a self-consistent effective field theory up to inflationary scale. This leads to a lower bound on the Higgs boson mass, Mh ≥ Mcrit. If Mh is more than a few hundreds of MeV above the critical value, the Higgs inflation predicts the universal values of inflationary indexes, r ' 0.003 and ns ' 0.97, independently on the Standard Model parameters. We show that in the vicinity of the critical point Mcrit the inflationary indexes acquire an essential dependence on the mass of the top quark mt and Mh. In particular, the amplitude of the gravitational waves can exceed considerably the universal value.

Inflection-point Higgs Inflation
Inflection-point inflation is an interesting possibility to realize a successful slow-roll inflation when inflation is driven by a single scalar field with its initial value below the Planck mass (φI . MP l). In order for a renormalization group (RG) improved effective λφ4 potential to develop an inflection-point, the quartic coupling λ(φ) must exhibit a minimum with an almost vanishing value i...
متن کاملOn initial conditions for the Hot Big Bang
We analyse the process of reheating the Universe in the electroweak theory where the Higgs field plays a role of the inflaton. We estimate the maximal temperature of the Universe and fix the initial conditions for radiation-dominated phase of the Universe expansion in the framework of the Standard Model (SM) and of the νMSM — the minimal extension of the SM by three right-handed singlet fermion...

متن کاملSpacetime 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 کاملTestability of the Higgs inflation scenario in a radiative seesaw model
The Higgs inflation scenario is an approach to realize the inflation, in which the Higgs boson plays a role of the inflaton without introducing a new particle. We investigate a Higgs inflation scenario in the so-called radiative seesaw model proposed by E. Ma. We find that a part of parameter regions where additional scalar fields can play a role of an inflaton is compatible with the current LH...
