Scalar damping in cosmological phase transitions
Andreas Ekstedt, Thomas Konstandin, Jorinde van de Vis
We outline how to calculate the scalar damping term during a cosmological phase transition from kinetic theory. We determine the scalar damping rate from top quarks and weak gauge…
Bubble Trouble: a Review on Electroweak Baryogenesis
Jorinde van de Vis, Jordy de Vries, Marieke Postma
The origin of the universal asymmetry between matter and antimatter remains a mystery. Electroweak baryogenesis is a well-motivated mechanism for generating the asymmetry dynamical…
Triple Higgs boson production and electroweak phase transition in the two-real-singlet model
Osama Karkout, Andreas Papaefstathiou, Marieke Postma +3
The production of three Higgs bosons at hadron colliders can be enhanced by a double-resonant effect in the -symmetric two-real-singlet extension of the Standard Mode…
Gravitational waves from supercooled phase transitions: dimensional transmutation meets dimensional reduction
Maciej Kierkla, Bogumila Swiezewska, Tuomas V. I. Tenkanen +1
Models with radiative symmetry breaking typically feature strongly supercooled first-order phase transitions, which result in an observable stochastic gravitational wave background…
Prediction of the bubble wall velocity for a large jump in degrees of freedom
Mikel Sanchez-Garitaonandia, Jorinde van de Vis
The bubble expansion velocity is an important parameter in the prediction of gravitational waves from first order phase transitions. This parameter is difficult to compute, especia…
