      abstract     = {A first measurement of the top quark spin asymmetry,
                      sensitive to the top quark polarisation, in t-channel single
                      top quark production is presented. It is based on a sample
                      of pp collisions at a centre-of-mass energy of 8 TeV
                      corresponding to an integrated luminosity of 19.7
                      fb$^{−1}$. A high-purity sample of t-channel single top
                      quark events with an isolated muon is selected. Signal and
                      background components are estimated using a fit to data. A
                      differential cross section measurement, corrected for
                      detector effects, of an angular observable sensitive to the
                      top quark polarisation is performed. The differential
                      distribution is used to extract a top quark spin asymmetry
                      of 0.26 ± 0.03(stat) ± 0.10(syst), which is compatible
                      with a p-value of 4.6\% with the standard model prediction
                      of 0.44.},
