EVAluation of the Equivalent Vector boson Approximation at highest energy colliders

Journal of High Energy Physics
Collider processes at the highest available partonic center-of-mass energies — 10 TeV and above — exhibit a new regime of electroweak interactions where electroweak gauge bosons mostly act as quasi-massless partons in vector boson fusion processes.

Transverse-momentum resummation at mixed QCD⊗QED NNLL accuracy for Z boson production at hadron colliders

Journal of High Energy Physics
We consider the transverse momentum (q T ) distribution of neutral charged bosons at hadron colliders. We perform the resummation of the logarithmically-enhanced effects due to simultaneous QCD and QED initial-state radiation, up to mixed next-to-next-to-

Electroweak Precision Physics from Low to High Energies

, 2007
Electroweak precision observables (EWPO) can give valuable information about the last unknown paramter of the Standard Model (SM), the Higgs-boson mass M_H^SM. EWPO can also restrict the parameter space of new physics models (NPM) such as the Minimal Supersymmetric Standard Model (MSSM).

Determination of the first-generation quark couplings at the Z-pole

Journal of High Energy Physics
Electroweak Precision Measurements are stringent tests of the Standard Model and sensitive probes to New Physics. Accurate studies of the Z-boson couplings to the first-generation quarks, which are currently constrained from LEP data to a few percent ...

Using the effective weak mixing angle as an input parameter in SMEFT

Journal of High Energy Physics
We implement electroweak renormalisation schemes involving the effective weak mixing angle to NLO in Standard Model Effective Field Theory (SMEFT). After developing the necessary theoretical machinery, we analyse a select set of electroweak precision ...
