NNLO QCD study of polarised $W^+W^−$ production at the LHC

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.
