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…
