    abstract = "We measure the polarization of W bosons from top-quark (t) decays into
final states with a charged lepton and jets, t (t) over bar ->
W(+)bW(-)(b) over bar -> lvbq (q) over bar (1)(b) over bar, using the
full Run II data set collected by the CDF II detector, corresponding to
an integrated luminosity of 8.7 fb(-1). A model-independent method
simultaneously determines the fraction of longitudinal (f(0)) and
right-handed (f(+)) W bosons to yield f(0) = 0.726 +/- 0.066(stat) +/-
0.067(syst) and f(+) = -0.045 +/- 0.044(stat) +/- 0.058(syst) with a
correlation coefficient of -0.69. Additional results are presented under
various standard model assumptions. No significant discrepancies with
the standard model are observed. DOI: 10.1103/PhysRevD.87.031104"
