In the course of follow-up work a mistake was discovered in the parameterization of the dependence of the W-boson helicity fractions in top quark decays. The dependence on two operator coefficients, Cφtb and CbW, was erroneously omitted. Inclusion of this dependence leads to significantly stronger bounds on these operators from the current data and modifies also the HL-LHC prospects. The expectations for e+e− colliders are not affected. We present corrected results in this erratum.
