Description
I present a model independent framework to study gravitational waves from cosmological first-order phase transitions. This framework is based on factorisation of phase transition dynamics at infrared, in three-dimensional effective theory, and temperature dependence encoded in dimensional reduction matching relations at ultraviolet. Within an infrared EFT, leading order behaviour of transition strength and bubble nucleation rate can be solved for generic polynomial potential. Combined with any mapping from UV to IR, the framework then provides a powerful and computationally fast setup to study phase transitions in wide class of beyond the Standard Model theories and dark sectors. Finally, I discuss how this framework can be combined with already existing codes based on automations of dimensional reduction for generic models.
