Electroweak Physics, Experimental Aspects

, 1999
Collider measurements on electroweak physics are summarised. Although the precision on some observables is very high, no deviation from the Standard Model of electroweak interactions is observed.

Hint for a Minimal Interaction Length in e+e−⟶γγ Annihilation in Total Cross Section of Center‐of‐Mass Energies 55‐207 GeV

Advances in High Energy Physics, Volume 2024, Issue 1, 2024.
The measurements of the total cross section of the e+e−⟶γγ(γ) reaction from the VENUS, TOPAS, OPAL, DELPHI, ALEPH, and L3 collaborations, collected between 1989 and 2003, are used to perform a χ2 test to validate the current quantum electrodynamics (QED) theory and search for possible deviations with the direct contact term annihilation. By observing a

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.
