Inflation and dark energy from gravity
Michal Artymowski, Zygmunt Lalak, Marek Lewicki
Inflationary paradigm has several issues, such as the pre-inflationary horizon problem or the eternal inflation. To avoid that the standard Starobinsky inflation has been extended…
Standard Model vacuum stability in the presence of gauge invariant nonrenormalizable operators
Zygmunt Lalak, Marek Lewicki, Paweł Olszewski
Analysis of the Standard Model effective potential can reveal certain properties of the UV completion of SM. We discuss the issue of stability of the SM potential after inclusion o…
Saddle point inflation from higher order corrections to Higgs/Starobinsky inflation
Michal Artymowski, Zygmunt Lalak, Marek Lewicki
We explore two saddle point inflationary scenarios in the context of higher order corrections related to different generalisations of general relativity. Firstly, we deal with Jord…
Saddle point inflation from theory
Michal Artymowski, Zygmunt Lalak, Marek Lewicki
We analyse several saddle point inflationary scenarios based on power-law models. We investigate inflation resulting from $f(R) = R + α_n M^{2(1-n)}R^n + α_{n+1}M^{-2n}R^{n+…
Features of electroweak symmetry breaking in five dimensional SUSY models
Zygmunt Lalak, Marek Lewicki, Moritz McGarrie +1
We explore the phenomenological predictions of a supersymmetric standard model, with a large extra dimension and unifying gauge couplings. The modified five dimensional renormalisa…
Hints of BSM physics in the SM effective potential
Zygmunt Lalak, Marek Lewicki, Pawel Olszewski
Investigation of the structure of the Standard Model effective potential at very large field strengths opens a window towards new phenomena and can reveal properties of the UV comp…
Higgs boson mass and high-luminosity LHC probes of supersymmetry with vectorlike top quark
Zygmunt Lalak, Marek Lewicki, James D. Wells
We consider an extension of the MSSM with an added vectorlike top partner. Our aim is to revisit to what extent such an extension can raise the Higgs boson mass through radiative c…
