Description

Effective Field Theory (EFT) is an essential framework to
connect new physics beyond the Standard Model at a high-energy scale with physical observables at a low-energy scale, e.g. Higgs measurements, Electroweak precision tests, etc.. In this talk, we will present the fundamental concepts of EFT from a bottom-up and a top-down point of view. We then focus on a key-point of the top-down EFT approach, the "matching." After that, we will present our new developments on the Universal One-Loop Effective Action (UOLEA), which is a framework that drastically simplifies the task to match a UV-model onto an EFT Lagrangian. In the last part of the presentation, we will briefly introduce our ongoing research on Anomalies in Effective Field Theory and their implications on the phenomenology of axions.
