Dimension-8 SMEFT contact-terms for vector-pair production via on-shell Higgsing

Journal of High Energy Physics
We derive the dimension-8 standard-model effective theory (SMEFT) contact terms relevant for vector-pair production at the LHC and lepton colliders.

Constraining anomalous Wtb and related SMEFT couplings using low-energy and electroweak precision observables

Journal of High Energy Physics
We investigate constraints on couplings of Standard Model effective field theory (SMEFT) operators contributing to Wtb effective vertex at tree level. We study the one-loop level impact of these couplings on the low-energy flavour changing charged and ...

Refinable modeling for unbinned SMEFT analyses

Machine Learning: Science and Technology
Abstract We present methods to estimate systematic uncertainties in unbinned large hadron collider (LHC) data analyses, focusing on constraining Wilson coefficients in the standard model effective field theory (SMEFT). Our approach also applies to broader parametric models of non-resonant phenomena beyond the standard model.
