Description

Summary of the research done as an MCnetITN3 PhD student.

Di-boson production processes play an important role in many Standard Model studies, including Higgs-boson and electroweak precision measurements. They also form an important background in searches for phenomena beyond the Standard Model. In this talk I will present a recent study on the inclusion of electroweak corrections to $pp→e^+e^-\mu^+\mu^-$ and $pp→e^+e^-\mu^+\mu^-j$, both at exact NLO and using two approximations: the EW virtual and EW Sudakov approach. We also consider for the first time the all-order NLL Sudakov corrections to the fixed-order prediction. Finally, I am going to present prediction for $pp→e^+e^-\mu^+\mu^-$+jets production based on merged NLO QCD matrix-element plus parton-shower simulations in the framework of the Sherpa event generator including electroweak corrections through the aforementioned approximations.
