Radiative symmetry breaking from the on-shell perspective

Autor: Sojka, Bartosz, Swiezewska, Bogumila

Models with classical scale symmetry, which feature radiative symmetry breaking, generically lead to a supercooled first-order phase transition in the early Universe resulting in a strong gravitational-wave signal, potentially observable by LISA. Thi

Scale-Invariant Model for Gravitational Waves and Dark Matter

Autor: Karam, Alexandros, Kierkla, Maciej, Świeżewska, Bogumiła

We have conducted a revised analysis of the first-order phase transition that is associated with symmetry breaking in a classically scale-invariant model that has been extended with a new $SU(2)$ gauge group. By incorporating recent developments in t

The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravitational-wave backgrounds and their implications for early universe and

Gravitational waves from conformal symmetry breaking

We consider the electroweak phase transition in the conformal extension of the standard model known as SU(2)cSM. Apart from the standard model particles, this model contains an additional scalar and gauge field that are both charged under the hidden

Conformal symmetry and the cosmological constant problem

Autor: Lucat, Stefano, Prokopec, Tomislav, Swiezewska, Bogumila

Publikováno v: Int. J. Mod. Phys. D 27 (2018) 1847014

We argue that, when a theory of gravity and matter is endowed with (classical) conformal symmetry, the fine tuning required to obtain the cosmological constant at its observed value can be significantly reduced. Once tuned, the cosmological constant
