The interaction rate of an ultrarelativistic active neutrino at a temperature below the electroweak crossover plays a role in leptogenesis scenarios based on oscillations between active neutrinos and GeV-scale sterile neutrinos. By making use of a Euclideanization property of a thermal light-cone correlator, we determine the O(g) correction to such an interaction rate in the high-temperature limit pi T >> m(W), finding a similar to 15...40% reduction. For a benchmark point, this NLO correction decreases the lepton asymmetries produced by similar to 1%. (C) 2019 The Author(s). Published by Elsevier B.V.
