Description
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.
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. The talk will discuss the details of this challenging measurement: Origin of photons at the LHC, treatment of pile-up and the modelling of the signal as well as that of the underlying event for background processes. An outlook on how this will play a role for future tests of the Standard Model and in searches of new physics at the TeV scale is given.
Connections will begin at 12:30 with the seminar beginning at 13:00.
