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…
