Gravitational wave and collider implications of electroweak baryogenesis aided by non-standard cosmology
Michał Artymowski, Marek Lewicki, James D. Wells
We consider various models realizing baryogenesis during the electroweak phase transition (EWBG). Our focus is their possible detection in future collider experiments and possible…
Scalar-tensor linear inflation
Michal Artymowski, Antonio Racioppi
We investigate two approaches to non minimally coupled gravity theories which present linear inflation as attractor solution: a) the scalar-tensor theory approach, where we look fo…
Initial conditions for inflation
Konstantinos Dimopoulos, Michal Artymowski
Within the -attractors framework we investigate scalar potentials with the same pole as the one featured in the kinetic term. We show that, in field space, this leads to directi…
Multi-phase induced inflation in theories with non-minimal coupling to gravity
Michal Artymowski, Zygmunt Lalak, Marek Lewicki
In this paper we investigate the induced inflation with two flat regions: one Starobinsky-like plateau in big field regime and one shorter plateau around the saddle point of the Ei…
Endlessly flat scalar potentials and -attractors
Michal Artymowski, Javier Rubio
We consider a minimally-coupled inflationary theory with a general scalar potential containing a stationary point of maximal order . We show…
Implications of extreme flatness in a general f(R) theory
Michal Artymowski, Zygmunt Lalak, Marek Lewicki
We discuss a modified gravity theory defined by . We consider both finite and infinite number of terms in the series while requiring that th…
