Effective field theory of precision electroweak physics at one loop

Physics Letters B, 2013
The one loop effects of two dimension-six operators on gauge boson self energies are computed within an effective field theory framework. These self energies are translated into effects on precision electroweak observables, and bounds are obtained on the operator coefficients.

From optimal observables to machine learning: an effective-field-theory analysis of e+e − → W+W − at future lepton colliders

Journal of High Energy Physics
We apply machine-learning techniques to the effective-field-theory analysis of the e + e − → W + W − processes at future lepton colliders, and demonstrate their advantages in comparison with conventional methods, such as optimal observables.

Boosting likelihood learning with event reweighting

Journal of High Energy Physics
Extracting maximal information from experimental data requires access to the likelihood function, which however is never directly available for complex experiments like those performed at high energy colliders.

New physics off the Z-pole: e + e − → f f ¯ $$ f\overline{f} $$ at Future Lepton Colliders

Journal of High Energy Physics
We explore the prospects for probing new physics (NP) beyond the Standard Model (SM) at the future lepton colliders through precision measurements of e + e − → f f ¯ $$ f\overline{f} $$ observables off the Z resonance.

Tracing the bottom electroweak dipole operators at future lepton colliders

Journal of High Energy Physics
While often omitted in the SMEFT analyses of electroweak measurements, the electroweak dipole operators of the bottom quark have been found to be important in some cases and are also related to processes involving the top quark. In this paper, we further

Constraining four-heavy-quark operators with top-quark, Higgs, and electroweak precision data

Journal of High Energy Physics
We establish constraints on the dimension-six four-heavy-quark operators in the Standard Model Effective Field Theory (SMEFT) by synthesising LHC measurements of top-quark and single-Higgs production with electroweak precision observables.
