Domain walls and gravitational waves in the Standard Model
Tomasz Krajewski, Zygmunt Lalak, Marek Lewicki +1
We study domain walls which can be created in the Standard Model under the assumption that it is valid up to very high energy scales. We focus on domain walls interpolating between…
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…
The impact of non-minimally coupled gravity on vacuum stability
Olga Czerwińska, Zygmunt Lalak, Marek Lewicki +1
We consider vacuum decay in the presence of a non-minimal coupling to gravity. We extend the usual thin-wall solution to include the non-minimal coupling. We also perform a full nu…
Gauge fixing and renormalisation scale independence of tunneling rate in abelian Higgs model and in the Standard Model
Zygmunt Lalak, Marek Lewicki, Paweł Olszewski
We explicitly show perturbative gauge fixing independence of the tunneling rate to a stable radiatively induced vacuum in the abelian Higgs model. We work with a class of gau…
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…
