We investigate the effects of a large-scale background hypermagnetic field on the electroweak phase transition. We propose a model in which an effective weak angle varies during the electroweak phase transition and upon its use we show that, although for the majority of the parameter space the phase transition is a crossover, there are some regions in which the phase transition occurs in two steps and can be first-order. We obtain all of the important quantities characterizing the details of the…

Filtered asymmetric dark matter during the Peccei-Quinn phase transition
Abstract In this paper, we propose a bubble filtering-out mechanism for an asymmetric dark matter scenario during the Peccei-Quinn (PQ) phase transition. Based on a QCD axion model, extended by


Strong electroweak phase transitions without collider traces
We discuss the question if the upcoming generation of collider and low-energy experiments can successfully probe the nature of the electroweak phase transition. In particular, we are interested in
The gravitational waves from the first-order phase transition with a dimension-six operator
We investigate in details the gravitational wave (GW) from the first-order phase transition (PT) in the extended standard model of particle physics with a dimension-six operator, which is capable of
Review of cosmic phase transitions: their significance and experimental signatures.
Different types of phase transitions that can appear in cosmic history, and their applications and experimental signatures in particular in the context of exciting gravitational waves, are reviewed, which could be potentially be constrained by LIGO/VIRGO, Kagra, LISA, and Decigo.
Gravitational waves from the sound of a first order phase transition.
It is found that the compression waves in the fluid continue to be a source of GWs long after the bubbles have merged, a new effect not taken properly into account in previous modeling of the GW source.
Hypermagnetic gyrotropy, inflation and the baryon asymmetry of the Universe
We investigate the production of the hypermagnetic gyrotropy when the electric and magnetic gauge couplings evolve at different rates, as it happens in the relativistic theory of the van der Waals
The generation of matter–antimatter asymmetries and hypermagnetic fields by the chiral vortical effect of transient fluctuations
We study the contribution of temperature-dependent chiral vortical effect to the generation and evolution of the hypermagnetic fields and the matter-antimatter asymmetries, in the symmetric phase of
Contribution of the chiral vortical effect to the evolution of the hypermagnetic field and the matter-antimatter asymmetry in the early Universe
In this paper, we study the contribution of the chiral vortical effect, in addition to that of the chiral magnetic effect, to the evolution of the hypermagnetic field and the matter-antimatter
Evolution of the baryon asymmetry through the electroweak crossover in the presence of a helical magnetic field
We elaborate upon the model of baryogenesis from decaying magnetic helicity by focusing on the evolution of the baryon number and magnetic field through the Standard Model electroweak crossover. The
