N2 - I report on the combination of measurements from CDF and D0 of the helicity fractions of W bosons from top quark decays. The result, when both the longitudinal (f0) and right-handed (f+) fractions are allowed to float, is f0 = 0.722 ± 0.081 [± 0.062 (stat.) ± 0.052 (syst.)] and f+ = -0.033 ± 0.046 [± 0.034 (stat.) ± 0.031 (syst.)], consistent with the Standard Model (SM) expectation. When one fraction is fixed to its SM value the results for the other fraction are f0 = 0.682 ± 0.057 [± 0.035 (stat.) ± 0.046 (syst.)] and f+ = -0.015 ± 0.035 [± 0.018 (stat.) ± 0.030 (syst.)].
