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 …

Cosmological aspects of Higgs vacuum metastability

T Markkanen, A Rajantie, S Stopyra - Frontiers in Astronomy and …, 2018 - frontiersin.org
The current central experimental values of the parameters of the Standard Model give rise to
a striking conclusion: metastability of the electroweak vacuum is favored over absolute …

A facility to Search for Hidden Particles at the CERN SPS: the SHiP physics case

S Alekhin, W Altmannshofer, T Asaka… - Reports on progress …, 2016 - iopscience.iop.org
This paper describes the physics case for a new fixed target facility at CERN SPS. The SHiP
(search for hidden particles) experiment is intended to hunt for new physics in the largely …

Investigating the near-criticality of the Higgs boson

D Buttazzo, G Degrassi, PP Giardino… - Journal of High Energy …, 2013 - Springer

Higgs mass and vacuum stability in the Standard Model at NNLO

G Degrassi, S Di Vita, J Elias-Miro, JR Espinosa… - Journal of High Energy …, 2012 - Springer
A bstract We present the first complete next-to-next-to-leading order analysis of the Standard
Model Higgs potential. We computed the two-loop QCD and Yukawa corrections to the …

Primordial black holes from single-field inflation: a fine-tuning audit

PS Cole, AD Gow, CT Byrnes… - Journal of Cosmology and …, 2023 - iopscience.iop.org
All single-field inflationary models invoke varying degrees of tuning in order to account for
cosmological observations. Mechanisms that generate primordial black holes (PBHs) from …

Higgs boson mass and new physics

F Bezrukov, MY Kalmykov, BA Kniehl… - Journal of High Energy …, 2012 - Springer
A bstract We discuss the lower Higgs boson mass bounds which come from the absolute
stability of the Standard Model (SM) vacuum and from the Higgs inflation, as well as the …

Higgs mass implications on the stability of the electroweak vacuum

J Elias-Miro, JR Espinosa, GF Giudice, G Isidori… - Physics Letters B, 2012 - Elsevier
