Effective Theory for a Heavy Scalar Coupled to the SM via Vector-Like Quarks
Stefan Alte, Matthias Koenig, Matthias Neubert
We illustrate the application of the recently developed SCET framework in the context of a specific model, in which the Standard Model (SM) is supplemented by a heavy s…
Consistent Searches for SMEFT Effects in Non-Resonant Dilepton Events
Stefan Alte, Matthias König, William Shepherd
Employing the framework of the Standard Model Effective Field Theory, we perform a detailed reinterpretation of measurements of the Weinberg angle in dilepton production as a searc…
Effective Field Theory after a New-Physics Discovery
Stefan Alte, Matthias König, Matthias Neubert
When a new heavy particle is discovered at the LHC or at a future high-energy collider, it will be interesting to study its decays into Standard Model particles using an effective…
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…
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…
Top Quark Charge Asymmetry: Searching for Light Axigluons in top pair + jet Production at the LHC
Stefan Alte, Stefan Berge, Hubert Spiesberger
We investigate the discovery potential of light color-octet bosons in the mass range of 100 - 400 GeV in exclusive top-pair plus jet production at the LHC. We study the impact of s…
