The ongoing Effective Field Theory (EFT) program at the LHC and elsewhere is motivated by streamlining the connection between experimental data and UV-complete scenarios of heavy new physics beyond the Standard Model (BSM). This connection is provided by matching relations mapping the Wilson coefficients of the EFT to the couplings and masses of UV-complete models. Building upon recent work on...
Effective field theories (EFTs) have become an essential tool in the search of new physics beyond the Standard Model. The calculation of the Wilson coefficients of the EFT for specific new physics models is usually performed by matching off-shell one-light-particle irreducible Green functions, which requires an off-shell basis of effective operators. This so-called Green's basis includes some...
Effective field theories have been gathering increasing attention in recent years. Within this field, the matching process is a key question for connecting this formalism with precise UV theories beyond the Standard Model. It is precisely here where functional methods have emerged as very effective tools, especially for automating computations.
So far, this method has been applied up to one...
While the matching of specific new physics scenarios onto the SMEFT framework is a well-understood procedure, the inverse problem, going from the SMEFT to UV scenarios, is more involved and requires the development of new methods to perform a systematic exploration of models. In this talk, I will discuss a diagrammatic approach to construct in an automated way a complete set of possible BSM...
