In recent years, theoretical and phenomenological studies with effective field theories have become a trending and prolific line of research in the field of high-energy physics. In…
Universal Scalar Leptoquark Action for Matching
Athanasios Dedes, Kostas Mantzaropoulos
In this study we present a universal effective action for one-loop matching of all scalar leptoquarks. We use both the Universal One-Loop Effective Action (UOLEA) and covariant dia…
SM EFT effects in Vector-Boson Scattering at the LHC
Athanasios Dedes, Paweł Kozów, Michał Szleper
The assumption that the Standard Model is an Effective Field Theory (SM EFT) of a more fundamental theory at a higher, than electroweak, energy scale, implies a growth of cross-sec…
Computing Tools for the SMEFT
Editors, :, Jason Aebischer +22
The increasing interest in the phenomenology of the Standard Model Effective Field Theory (SMEFT), has led to the development of a wide spectrum of public codes which implement aut…
Proposal for the validation of Monte Carlo implementations of the standard model effective field theory
Gauthier Durieux, Ilaria Brivio, Fabio Maltoni +38
We propose a procedure to cross-validate Monte Carlo implementations of the standard model effective field theory. It is based on the numerical comparison of squared amplitudes com…

Athanasios Dedes, Dimitrios Karamitros, Vassilis C. Spanos
We perform a detailed study of an effective field theory which includes the Standard Model particle content extended by a pair of Weyl fermionic SU(2)-doublets with opposite hyperc…
Mass Insertions vs. Mass Eigenstates calculations in Flavour Physics
A. Dedes, M. Paraskevas, J. Rosiek +2
We present and prove a theorem of matrix analysis, the Flavour Expansion Theorem (or FET), according to which, an analytic function of a Hermitian matrix can be expanded polynomial…
Rare Top-quark Decays to Higgs boson in MSSM
