Matrix element method at NLO: A fine proof of concept in POWHEG
Ulrich Haisch, Jakob Linder, Luc Schnell +2
The matrix element method (MEM) provides a fully probabilistic approach to confront experimental events with theory, retaining all correlations in the scattering matrix element. Wh…

Precision tests of third-generation four-quark operators: one- and two-loop matching
Ulrich Haisch, Luc Schnell
We calculate the one- and two-loop matching corrections in the Standard Model effective field theory (SMEFT) that impact electroweak precision measurements and flavour physics obse…

SMEFT at NNLOPS: production
Rhorry Gauld, Ulrich Haisch, Luc Schnell
In the context of the Standard Model effective field theory (SMEFT) the next-to-next-to-leading (NNLO) QCD corrections to the Higgsstrahlungs () processes in hadronic collision…
