If the Physics Beyond the Standard Model is decoupled at higher energies, the Standard Model as an effective field theory, the SM EFT, is a pertinent framework for phenomenology. The BSM effects on observables are parametrized by the Wilson coefficients of dimension-6 operators, and bounds on their values can be placed from a global fit to experimental measurements. Integrating out heavy...

Effective field theories seem to be one of the best choices in order to look for new physics at the TeV scale and beyond, provided that direct searches finally are unsuccessful. We build an effective Lagrangian with the particle content of the Standard Model and incorporate the most general colour-singlet heavy fields with bosonic quantum numbers $J^P=0^\pm,\,1^\pm$ in triplet and singlet...

We discuss the top-down calculation of the Standard Model effective Lagrangian at one loop. After emphasizing the need matching in theories with linear couplings we describe Match Maker, an automated tool to perform tree-level and one-loop matching calculations in arbitrary extensions of the Standard Model.

A non-perturbative mechanism for dynamical generation of the mass of elementary particles, both fermions and weak bosons, is presented in a simplified gauge model. Within this framework, which is under test by numerical simulations, elementary particle masses arise naturally in a certain chiral symmetry limit with a magnitude that is controlled by the strongest interaction each particle...
