Higgs inflation

J Rubio - Frontiers in Astronomy and Space Sciences, 2019 - frontiersin.org
The properties of the recently discovered Higgs boson together with the absence of new
physics at collider experiments allows us to speculate about consistently extending the …

Selected topics in scalar–tensor theories and beyond

I Quiros - International Journal of Modern Physics D, 2019 - World Scientific
Scalar fields have played an important role in the development of the fundamental theories
of physics as well as in other branches of physics such as gravitation and cosmology. For a …

Higgs inflation is still alive after the results from BICEP2

Y Hamada, H Kawai, K Oda, SC Park - Physical review letters, 2014 - APS
The observed value of the Higgs boson mass indicates that the Higgs potential becomes
small and flat at the scale around 10 17 GeV. Having this fact in mind, we reconsider the …

Planck scale black hole dark matter from Higgs inflation

S Räsänen, E Tomberg - Journal of Cosmology and Astroparticle …, 2019 - iopscience.iop.org
We study the production of primordial black hole (PBH) dark matter in the case when the
Standard Model Higgs coupled non-minimally to gravity is the inflaton. PBHs can be …

Higgs inflation with loop corrections in the Palatini formulation

S Räsänen, P Wahlman - Journal of Cosmology and Astroparticle …, 2017 - iopscience.iop.org
We compare Higgs inflation in the metric and Palatini formulations of general relativity, with
loop corrections treated in a simple approximation. We consider Higgs inflation on the …

[HTML][HTML] Classical and quantum initial conditions for Higgs inflation

A Salvio, A Mazumdar - Physics Letters B, 2015 - Elsevier
We investigate whether Higgs inflation can occur in the Standard Model starting from natural
initial conditions or not. The Higgs has a non-minimal coupling to the Ricci scalar. We …

Non-minimal coupling in Higgs–Yukawa model with asymptotically safe gravity

K Oda, M Yamada - Classical and Quantum Gravity, 2016 - iopscience.iop.org
We study the fixed-point structure of the Higgs–Yukawa model, with its scalar being non-
minimally coupled to the asymptotically safe gravity, using the functional renormalization …

Higgs inflation from Standard Model criticality

Y Hamada, H Kawai, K Oda, SC Park - Physical Review D, 2015 - APS
The observed Higgs mass MH= 125.9±0.4 GeV leads to the criticality of the standard model,
that is, the Higgs potential becomes flat around the scale 1 0 17–18 GeV for the top mass …

Type II seesaw leptogenesis

ND Barrie, C Han, H Murayama - Journal of High Energy Physics, 2022 - Springer
A bstract The Type II Seesaw Mechanism provides a minimal framework to explain the
neutrino masses involving the introduction of a single triplet Higgs to the Standard Model …

Dimensional transmutation in gravity and cosmology

A Salvio - International Journal of Modern Physics A, 2021 - World Scientific
We review (and extend) the analysis of general theories of all interactions (gravity included)
where the mass scales are due to dimensional transmutation. Quantum consistency requires …
