Description
The upcoming launch of LISA has recently strengthened the interest in exploring Standard Model extensions where a gravitational wave-producing, strong first-order electroweak phase transition (SFOEWPT) occurs in the early universe. One of the preferred approaches to the study of thermally induced FOPTs is through the construction of a dimensionally reduced effective field theory (3dEFT). In this talk we will summarize the key aspects of this approach. We shall provide a rigorous perturbative method to compute the essential magnitudes for modeling the GW production during a SFOPT. We will discuss the importance of including higher-order effective operators in these computations, which drastically change the predictions of GW-related magnitudes and are, as far as the authors know, often overlooked in the current literature.
