Future collider constraints on top-quark operators

Journal of High Energy Physics
In this paper we present updated constraints on the top-quark sector of the Standard Model Effective Field Theory using data available from Tevatron, LEP and the LHC.

Electroweak precision data as a gateway to light higgsinos

Journal of High Energy Physics
We investigate the prospects of probing weak-scale higgsinos through electroweak precision measurements at a future e + e − collider. In the Minimal Supersymmetric Standard Model, higgsinos mix with winos and binos after electroweak symmetry breaking ...

Precision electroweak physics at the LHeC and FCC-eh

, 2022
The proposed electron-proton collider experiments LHeC and FCC-eh at CERN are the highest resolution microscopes that can be realised in the present century and they would represent a really unique research facility. We exploit simulated neutral-current and charged-current deep-inelastic scattering data of the LHeC and the FCC-eh and examine their ...

Linear Standard Model extensions in the SMEFT at one loop and Tera-Z

Journal of High Energy Physics
Linear Standard Model (SM) extensions, defined as new particles that can couple linearly to SM fields, form a motivated and finite set of simplified models for exploring phenomenology Beyond the SM (BSM).

Precision Electroweak Physics at Future Collider Experiments

, 1996
We present an overview of the present status and prospects for progress in electroweak measurements at future collider experiments leading to precision tests of the Standard Model of Electroweak Interactions. Special attention is paid to the measurement of the W mass, the effective weak mixing angle, and the determination of the top quark mass.

An EWPD SMEFT likelihood for the LHC — and how to improve it with measurements of W and Z boson properties

Journal of High Energy Physics
This paper presents a computer code for analyzing electroweak precision data (EWPD) in the framework of the Standard Model Effective Field Theory (SMEFT), highlights the importance of recent ATLAS and CMS precision measurements, and introduces a novel ...

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.
