W-boson helicity fractions in top decay as probes of dimension-6 and dimension-8 SMEFT operators
Including dimension-8 SMEFT operators alters the allowed parameter space for dimension-6 coefficients in fits to top-decay helicity fractions due to non-trivial correlations and degeneracies at O(Λ^{-4}).
