Abstract: 

The status quo of particle physics after the first data taking at the Large Hadron Collider is: a light Higgs particle has been discovered that is perfectly compatible with the electroweak Standard Model (SM). While this is undoubtedly a historic step in particle physics, it is not entirely satisfactory, as in its current state the SM leaves many questions unanswered. 

Strides that have been made towards an experimental global effective field theory (EFT) fit at the Large Hadron Collider (LHC). EFTs are used to systematically extend the SM Lagrangian and search for new physics phenomena beyond the energy reach of the LHC. The observation of WW production in photon collisions, yy->WW, represents a mile stone in the quest to fully characterize the electroweak sector of the SM, as well as other challenging measurements with W bosons in the final state. 

The talk will discuss the details of these challenging measurements and give an outlook on how they will be used in combinations for future tests of the Standard Model and in searches of new physics at the TeV scale.
