SUMMARY:Precision Physics with Polarised W-bosons at the LHC - Andrei Pope

DESCRIPTION:The longitudinal polarisation of weak bosons originates from t
 he Electroweak symmetry breaking mechanism and thus represents a handle on
  new physics. Direct observation of boson polarisation is not possible\, b
 ut one finds its trace left in kinematical distributions\, which we utilis
 e to separate longitudinal and transverse modes.\nI will explore how W-bos
 on polarisation is defined and can be accessed at the LHC\, and present ou
 r recent studies at NNLO precision for W+j and WW processes. We will discu
 ss the impact and effects of higher-order corrections. Finally\, I will to
 uch upon the topic of W-mass measurements in the context of its link to po
 larisations\, and present our latest results which provide state-of-the-ar
 t theoretical input for the future mass measurements at the LHC.
