Description
In this talk I will discuss our recent advancements, and the technical challenges involved, in the precise determination of the high-temperature limit of the Standard Model Effective Field Theory (SMEFT). Through a comparison with lattice data, we provide evidence that the SMEFT may undergo a first-order phase transition even in the absence of direct modifications of the Higgs potential. In such case, however, our analysis implies that the phase transition is not sufficiently strong, narrowing down the new physics that allows for electroweak baryogenesis and the production of observable gravitational waves.
