Abstract
Longitudinal polarisation of the weak bosons is a direct consequence of
Electroweak symmetry breaking mechanism providing an insight into its nature,
and is instrumental in searches for physics beyond the Standard Model. We
perform a polarisation study of the diboson production in the $p p \to
e^+\nu_e\mu^-\bar\nu_\mu$ process at NNLO QCD in the fiducial setup inspired by
experimental measurements at ATLAS. This is the first polarisation study at
NNLO. We employ the double-pole approximation framework for the polarised
calculation, and investigate NNLO effects arising in differential
distributions.
