The Simplest B Decay, Precisely
Claudia Cornella, Max Ferré, Matthias König +1
We derive the QCDQED factorization theorem governing the leptonic decay at all orders in and . Electromagnetic corrections to this decay prob…
The Inverted Pendulum as a Classical Analog of the EFT Paradigm
Martin Beneke, Matthias König, Martin Link
The inverted pendulum is a mechanical system with a rapidly oscillating pivot point. Using techniques similar in spirit to the methodology of effective field theories, we derive an…
Computing Tools for Effective Field Theories
Jason Aebischer, Matteo Fael, Javier Fuentes-Martín +30
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…
Structure-Dependent QED Effects in Exclusive B Decays at Subleading Power
Claudia Cornella, Matthias König, Matthias Neubert
We derive a factorization theorem for the structure-dependent QED effects in the weak exclusive process , i.e., effects probing the internal structure of th…
Exclusive Weak Radiative Higgs Decays in the Standard Model and Beyond
Stefan Alte, Matthias König, Matthias Neubert
We perform a detailed study of the exclusive Higgs decays and , where is a pseudoscalar or vector meson, using the QCD factorization approach. We allow for t…
Exclusive Radiative Z-Boson Decays to Mesons with Flavor-Singlet Components
Stefan Alte, Matthias Koenig, Matthias Neubert
We present a detailed study of the exclusive radiative decays employing the QCD factorization approach. We derive a factorization formula for the decay amplitud…
Rare Z Decays and Neutrino Flavor Universality
Gauthier Durieux, Yuval Grossman, Matthias König +2
We study rare four-body decays of the Z-boson involving at least one neutrino and one charged lepton. Large destructive interferences make these decays very sensitive to the Z coup…
Neutrino Anarchy and Renormalization Group Evolution
Vedran Brdar, Matthias König, Joachim Kopp
The observed pattern of neutrino mixing angles is in good agreement with the hypothesis of neutrino anarchy, which posits that Nature has chosen the entries of the leptonic mixing…
Exclusive Radiative Higgs Decays as Probes of Light-Quark Yukawa Couplings
Matthias Koenig, Matthias Neubert
We present a detailed analysis of the rare exclusive Higgs-boson decays into a single vector meson and a photon and investigate the possibility of using these processes to probe th…
Exclusive Radiative Decays of W and Z Bosons in QCD Factorization
Yuval Grossman, Matthias König, Matthias Neubert
We present a detailed theoretical analysis of very rare, exclusive hadronic decays of the electroweak gauge bosons V=W, Z from first principles of QCD. Our main focus is on the rad…
Dipole operator constraints on composite Higgs models
Matthias König, Matthias Neubert, David M. Straub
Flavour- and CP-violating electromagnetic or chromomagnetic dipole operators in the quark sector are generated in a large class of new physics models and are strongly constrained b…
