THE NEXT TO MINIMAL SUPERSYMMETRIC STANDARD MODEL WITH A MODERATE STOP MASS

, 2008
In this thesis we analize the Next to Minimal Supersymmetric Standard Model (NMSSM), looking for a natural electroweak symmetry breaking. Focusing on a moderate stop mass and requiring perturbative unification of the gauge couplings (which after all is a

High precision simulations of electroweak physics with Sherpa [PDF]

, 2015
One vital theoretical tool in the ever-improving description of particle physics is Monte Carlo event simulation. With the CERN LHC currently exploiting the highest energies in any human-made experiment, with unprecedented precision for a range of ...

Electroweak Physics at the LHC - Experimental Overview

At the LHC, the electroweak theory of the Standard Model of particle physics can be probed through either precision measurements of $W$ and $Z$ boson production or through gauge-boson self-interactions at high energy in multiboson processes. In this talk,

Precision Electroweak Measurements at FCC-ee

, 2019
International audienceWith the discovery of the Higgs boson at the LHC in 2012, all fundamental parameters of the Standard Model Theory (SMT) have been experimentally measured. Then the global fits of the electroweak sector provide a powerful test of the

Electron-positron annihilation into heavy leptons at two loops

Journal of High Energy Physics
We calculate the NNLO QED corrections to the C-even part of differential cross section of e + e − → μ + μ − process. We neglect power corrections in the electron mass and obtain the result in terms of Goncharov’s polylogarithms.

Mixed QCD-EW corrections to W-pair production at electron-positron colliders

Journal of High Energy Physics
The discrepancy between the CDF measurement and the Standard Model theoretical prediction for the W-boson mass underscores the importance of conducting high-precision studies on the W boson, which is one of the predominant objectives of proposed future e

Electroweak precision physics from LEP to LHC and ILC

, 2009
Electroweak precision physics is reviewed from the LEP era with implications for Higgs bosons and supersymmetry, together with expectations for the LHC and a future Linear Collider ...

Electroweak Physics

, 2002
The status of precision electroweak measurements as of summer 2002 is reviewed. The recent results on the anomalous magnetic moment of the muon and on neutrino-nucleon scattering are discussed. Precision results on the electroweak interaction obtained by

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.

Fermionic electroweak two-loop corrections to Drell-Yan and related processes

Journal of High Energy Physics
We perform a complete calculation of the next-to-next-to-leading order (NNLO) electroweak fermionic corrections to fermion-pair production processes, where “fermionic” refers to contributions with closed fermion loops.
