Effective Quantum Field Theory and SMEFT
Anisha, Anke Biekötter, Matthias König
We introduce the basics of Effective Field Theories, using the Standard Model Effective Field Theory as our central example. The first part of this chapter gives a pedagogical intr…
A Proof of Concept for Matchete: An Automated Tool for Matching Effective Theories
Javier Fuentes-Martín, Matthias König, Julie Pagès +2
Studying the impact of new-physics models on low-energy observables necessitates matching to effective field theories at the relevant mass thresholds. We introduce the first public…
Evanescent Operators in One-Loop Matching Computations
Javier Fuentes-Martín, Matthias König, Julie Pagès +2
Effective Field Theory calculations used in countless phenomenological analyses employ dimensional regularization, and at intermediate stages of computations, the operator bases ex…
SuperTracer: A Calculator of Functional Supertraces for One-Loop EFT Matching
Javier Fuentes-Martin, Matthias König, Julie Pagès +2
We present SuperTracer, a Mathematica package aimed at facilitating the functional matching procedure for generic UV models. This package automates the most tedious parts of one-lo…
Hunting for imprints on the dimuon spectrum
Claudia Cornella, Gino Isidori, Matthias König +3
We investigate the possibility of indirectly constraining the decay rate using precise data on the dimuon spectrum. To this end, we es…
Effective Field Theory after a New-Physics Discovery
Matthias König
After the discovery of a new resonance, its couplings to the Standard Model (SM) need to be described by the means of an effective theory, appropriately constructed to separate its…
Exclusive Radiative Decays of Z Bosons in QCD Factorization
Stefan Alte, Yuval Grossman, Matthias König +1
We discuss the very rare, exclusive hadronic decays of a Z boson into a meson and a photon. The QCD factorization approach allows to organize the decay amplitude as an expansion in…
