The construction of 3D EFTs for phase transition (PT) computations has been taken to unprecedented levels of precision in the recent years, considering effects up to 3-loop order. However, the contributions from higher-dimensional effective operators (EO) that arise at the same order in the power counting have been generally neglected in the literature.

In this talk, we will analyze the effect of these EO in a model resembling the Higgs sector of the SMEFT up to dimension 6, in the strong transition regime. Finally, we will highlight the challenges to overcome to extend these computations to more complex models..
