Description
The limitations of the Standard Model (SM) continue to drive the search for new physics. In the absence of direct evidence, performing a comparative analysis of various 'well-motivated' Beyond Standard Model (BSM) models under a common framework is valuable. Effective Field Theories (EFTs) offer a robust approach for such analyses, providing essential tools for systematic exploration, at distinct energy scales. This talk has two main objectives: first, to discuss the computation of the universal effective action up to dimension-eight using the Heat-Kernel method, advancing precision beyond dimension-six results; and second, to examine cases where dimension-eight contributions become more significant than dimension-six terms. Finally, we will explore two UV models containing heavy scalars - a complex scalar triplet and a doublet - as examples to show how integrating out heavy scalars and matching to UV parameters can effectively distinguish between these models.
