Résumé |
The large amount of high quality data collected at the LHC, and in perspective at
future lepton colliders, will bring the experimental error of several observables
at the (sub)percent level, also in the TeV mass range.
The combination of this information, together with the precision studies of W and
Z bosons properties, will allow a very severe test of the EW
Standard Model and establish a robust benchmark relevant for the searches of New
Physics signals.
I will illustrate recent results about the evaluation of the second order mixed
QCD-electroweak quantum corrections to the production of a lepton pair at hadron
colliders, the so called Drell-Yan process.
I will describe the theoretical and computational challenges in the study of the
virtual corrections to this process, and will present a phenomenological
discussion for several observables of interest.
The prospects towards the completion of the calculation of the full set of second
order corrections of purely electroweak origin, crucial in the precision physics
program at future lepton colliders, will be presented. |
