      abstract     = {A measurement of the W boson helicity is presented, where
                      the W boson originates from the decay of a top quark
                      produced in pp collisions. The event selection, optimized
                      for reconstructing a single top quark in the final state,
                      requires exactly one isolated lepton (muon or electron) and
                      exactly two jets, one of which is likely to originate from
                      the hadronization of a bottom quark. The analysis is
                      performed using data recorded at a center-of-mass energy of
                      8 TeV with the CMS detector at the CERN LHC in 2012. The
                      data sample corresponds to an integrated luminosity of 19.7
                      fb$^{−1}$. The measured helicity fractions are F$_{L}$ =
                      0.298 ± 0.028 (stat) ± 0.032(syst), F$_{0}$ = 0.720 ±
                      0.039 (stat) ± 0.037(syst), and F$_{R}$ = −0.018 ± 0.019
                      (stat) ± 0.011(syst). These results are used to set limits
                      on the real part of the tWb anomalous couplings, g$_{L}$ and
                      g$_{R}$.},
