description: The polarisation of prompt $ψ(2S)$ mesons is measured by performing an angular analysis of $ψ(2S)\rightarrow μ^{+} μ^{-}$ decays using proton-proton collision data, corresponding to an integrated luminosity of 1.0 fb$^{-1}$, collected by the LHCb detector at a centre-of-mass energy of 7 TeV. The polarisation is measured in bins of transverse momentum $p_\mathrm{T}$ and rapidity $y$ in the kinematic region $3.5
