The longitudinal polarisation of weak bosons originates from the Electroweak symmetry breaking mechanism and thus represents a handle on new physics. Direct observation of boson polarisation is not possible, but one finds its trace left in kinematical distributions, which we utilise to separate longitudinal and transverse modes. I will explore how W-boson polarisation is defined and can be accessed at the LHC , and present our recent studies at NNLO precision for W+j and WW processes. We will discuss the impact and effects of higher-order corrections. Finally, I will touch upon the topic of W-mass measurements in the context of its link to polarisations, and present our latest results which provide state-of-the-art theoretical input for the future mass measurements at the LHC .
