Light inflaton model in a metastable Universe
Fedor Bezrukov, Abigail Keats
We minimally extend the SM with a Z symmetric potential containing a single scalar field, serving as our inflaton with a quartic self-coupling. In the model we have symmetry br…
Heavy Light Inflaton and Dark Matter Production
Fedor Bezrukov, Abigail Keats
We study the minimal extension of the SM by a scalar with quartic interaction serving as an inflaton. For the model where scale symmetry is broken only in the inflaton sector, the…
A heatwave affair: mixed Higgs- preheating on the lattice
Fedor Bezrukov, Chris Shepherd
We use lattice methods to perform the first nonlinear study of preheating in -healed Higgs inflation for "-like" parameters and where th…
No Miracle in Gravity Portals
Fedor Bezrukov, Sergey Demidov, Dmitry Gorbunov
The idea of dark matter particles coupled only gravitationally is minimalist yet viable. Assuming an additional -breaking linear coupling of scalar curvature to the dark matte…
Direct comparison of sterile neutrino constraints from cosmological data, disappearance data and appearance data in a model
Matthew Adams, Fedor Bezrukov, Jack Elvin-Poole +4
We present a quantitative, direct comparison of constraints on sterile neutrinos derived from neutrino oscillation experiments and from Planck data, interpreted assuming standard c…
Scalar induced resonant sterile neutrino production in the early Universe
F. Bezrukov, A. Chudaykin, D. Gorbunov
It has been recently suggested \cite{Bezrukov:2017ike,Bezrukov:2018wvd} that a cosmic scalar field can completely change the keV-scale sterile neutrino production in the early Univ…
