From friction scaling to an efficient method for estimating bubble wall velocity

Tomasz Krajewski, Marek Lewicki, Marco Merchand +2

We present a unified description of first-order cosmological phase transition dynamics that links the phenomenological friction model employed in hydrodynamic simulations to the mi…

Electroweak symmetry non-restoration and suppressed dark radiation in Supersymmetric Twin Higgs model

Marcin Badziak, Keisuke Harigaya, Ignacy Nałęcz

We investigate a possibility of electroweak symmetry non-restoration (SNR) below the Twin electroweak scale (TeV) within the Twin Higgs model. We focus on supersymmetric exte…

Steady-state bubbles beyond local thermal equilibrium

Tomasz Krajewski, Marek Lewicki, Ignacy Nałęcz +1

We investigate the hydrodynamic solutions for expanding bubbles in cosmological first-order phase transitions going beyond local thermal equilibrium approximation. Under the assump…

One-loop Renormalization Group Equations in Generic Effective Field Theories. Part I: Bosonic Operators

Mikołaj Misiak, Ignacy Nałęcz

We consider a generic class of effective quantum field theories with arbitrary gauge groups and scalar matter fields. In such theories, we derive the one-loop Renormalization Group…

Phase transition and gravitational waves in maximally symmetric composite Higgs model

Avik Banerjee, Marco Merchand, Ignacy Nałęcz

In this paper we study phase transitions in a maximally symmetric composite Higgs model with next-to-minimal coset, where a pseudoscalar singlet emerges alongside the Higgs doublet…
