Electroweak Corrections for W+ W− Scattering — •Robert Franken — JMU Würzburg
Vector boson scattering (VBS) processes are a very good testing ground for the validity of the Standard Model (SM) and electroweak symmetry breaking in general. Over the last few years, Atlas and LHC have been able to measure the cross sections of VBS. To search for deviations, it is important to have precise predictions for VBS processes within the SM. Whilst only the QCD NLO predictions were available for some time, recently electroweak corrections have become available for the scattering of like-sign W bosons and W and Z bosons and turned out to be at the level of 15% for fiducial cross sections. In this talk we report on our efforts to calculate the NLO EW corrections to opposite sign WW scattering and the complete NLO corrections to the process p p → e+ µ− νe νµj j.
