Higgs domain walls in the thermal background
Tomasz Krajewski, Zygmunt Lalak, Marek Lewicki +1
Most cosmological models predict that the universe was hot and dense at the early stages of it's evolution. In this paper we analyse the influence of the thermal bath of Standard M…
Vanishing trace anomaly in flat spacetime
Zygmunt Lalak, Paweł Olszewski
Quantum scale invariant regularization is a variant of dimensional regularization where the renormalization scale is treated as a dynamical field. But, rather than be regarded as a…
Domain walls in the extensions of the Standard Model
Tomasz Krajewski, Zygmunt Lalak, Marek Lewicki +1
Our main interest is the evolution of domain walls of the Higgs field in the early Universe. The aim of this paper is to understand how dynamics of Higgs domain walls could be infl…
Non-minimally coupled gravity and vacuum stability
Olga Czerwińska, Zygmunt Lalak, Marek Lewicki +1
We investigate the properties of vacuum decay taking into account a non-minimal coupling to gravity. We extend the standard thin-wall solution to include the non-minimal coupling a…
Standard Model with spontaneously broken quantum scale invariance
D. M. Ghilencea, Z. Lalak, P. Olszewski
We explore the possibility that scale symmetry is a quantum symmetry that is broken only spontaneously and apply this idea to the Standard Model (SM). We compute the quantum correc…
Two-loop scale-invariant scalar potential and quantum effective operators
D. M. Ghilencea, Z. Lalak, P. Olszewski
Spontaneous breaking of quantum scale invariance may provide a solution to the hierarchy and cosmological constant problems. In a scale-invariant regularization, we compute the two…
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…
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…
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…
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…
Higher-order scalar interactions and SM vacuum stability
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…
