Dijet bounds on third-generation four-quark operators
Maximilian Freiheit, Ulrich Haisch
We use dijet measurements from the Large Hadron Collider to constrain ten third-generation four-quark operators in the Standard Model effective field theory. At tree level, only th…
How large are hadronic contributions to ?
Ulrich Haisch
The decay of the Higgs boson into two photons, , is a loop-induced process within the Standard Model, predominantly mediated by loops of bosons and top quarks. While…
Precision tests of third-generation four-quark operators: and
Ulrich Haisch, Marco Niggetiedt
We compute the two-loop contributions to Higgs production via gluon-gluon fusion () and Higgs decay into two photons (), arising from third-generation four-quar…
Polarized-boson pairs at NLO in the SMEFT
Ulrich Haisch, Jakob Linder, Giovanni Pelliccioli +2
We present a computation of diboson production in the channel at the Large Hadron Collider (LHC), incorporating leptonic decays of the gauge bosons and considering interm…
Neural simulation-based inference of the Higgs trilinear self-coupling via off-shell Higgs production
Aishik Ghosh, Maximilian Griese, Ulrich Haisch +1
One of the forthcoming major challenges in particle physics is the experimental determination of the Higgs trilinear self-coupling. While efforts have largely focused on on-shell d…
A new probe of the quartic Higgs self-coupling
Ulrich Haisch, Aparna Sankar, Giulia Zanderighi
We calculate the corrections to the Higgs wave-function renormalization constant arising from modified cubic, quartic, and quintic Higgs self-couplings up to the two-loop level. Us…
Higgs production from anomalous gluon dynamics
Ulrich Haisch
We present a two-loop analysis of the contributions to Higgs production via gluon-gluon fusion arising from the triple-gluon operator in the Standard Model effective field theory (…
