WallGo investigates: Theoretical uncertainties in the bubble wall velocity

Jorinde van de Vis, Philipp Schicho, Lauri Niemi +3

We examine theoretical uncertainties in state-of-the-art calculations of the bubble wall velocity during first-order cosmological phase transitions. By utilising the software WallG…

How fast does the WallGo? A package for computing wall velocities in first-order phase transitions

Andreas Ekstedt, Oliver Gould, Joonas Hirvonen +4

WallGo is an open source software for the computation of the bubble wall velocity in first-order cosmological phase transitions. It also computes the energy budget available for th…

Investigating two-loop effects for first-order electroweak phase transitions

Lauri Niemi, Tuomas V. I. Tenkanen

We study first-order electroweak phase transitions in the real-singlet extended Standard Model, for which non-zero mixing between the Higgs and the singlet can efficiently strength…

Nonperturbative study of the electroweak phase transition in the real scalar singlet extended Standard Model

Lauri Niemi, Michael J. Ramsey-Musolf, Guotao Xia

We perform a nonperturbative lattice study of the electroweak phase transition in the real singlet scalar extension of the Standard Model.We consider both the heavy and light singl…

Shape of the hot topological charge density spectral function

M. Laine, L. Niemi, S. Procacci +1

After motivating an interest in the shape of the topological charge density spectral function in hot Yang-Mills theories, we estimate it with the help of thermally averaged classic…

Singlet-assisted electroweak phase transition at two loops

Lauri Niemi, Philipp Schicho, Tuomas V. I. Tenkanen

We investigate the electroweak phase transition in the real-singlet extension of the Standard Model at two-loop level, building upon existing one-loop studies. We calculate the eff…
