Domain walls in the extensions of the Standard Model

Understand

Our main interest is the evolution of domain walls of the Higgs field in the early Universe.

• The aim of this paper is to understand how dynamics of Higgs domain walls could be influenced by yet unknown interactions from beyond the Standard Model.
• We assume that the Standard Model is valid up to certain, high, energy scale $\Lambda$ and use the framework of the effective field theory to describe physics below that scale.
• Performing numerical simulations with different values of the scale $\Lambda$ we are able to extend our previous analysis and determine its range of validity.
