Standard Model Higgs boson mass from inflation
Fedor L. Bezrukov, Amaury Magnin, Mikhail Shaposhnikov
We analyse one-loop radiative corrections to the inflationary potential in the theory, where inflation is driven by the Standard Model Higgs field. We show that inflation is possib…
Quantum scale invariance on the lattice
Mikhail E. Shaposhnikov, Igor I. Tkachev
We propose a scheme leading to a non-perturbative definition of lattice field theories which are scale-invariant on the quantum level. A key idea of the construction is the replace…
Sterile neutrinos in cosmology and how to find them in the lab
Mikhail Shaposhnikov
A number of observed phenomena in high energy physics and cosmology lack their resolution within the Standard Model of particle physics. These puzzles include neutrino oscillations…
Quantum scale invariance, cosmological constant and hierarchy problem
Mikhail Shaposhnikov, Daniel Zenhausern
We construct a class of theories which are scale invariant on quantum level in all orders of perturbation theory. In a subclass of these models scale invariance is spontaneously br…
Scale invariance, unimodular gravity and dark energy
Mikhail Shaposhnikov, Daniel Zenhausern
We demonstrate that the combination of the ideas of unimodular gravity, scale invariance, and the existence of an exactly massless dilaton leads to the evolution of the universe su…
Sterile neutrino dark matter as a consequence of nuMSM-induced lepton asymmetry
M. Laine, M. Shaposhnikov
It has been pointed out in ref.[1] that in the nuMSM (Standard Model extended by three right-handed neutrinos with masses smaller than the electroweak scale), there is a corner in…
