Abstract
We calculate the leading-logarithmic and next-to-leading-logarithmic electroweak corrections to the charm-top-quark contribution to the effective Lagrangian, relevant for the parameter . We find that these corrections lead to a shift in the corresponding Wilson coefficient. Moreover, our calculation removes an implicit ambiguity in the standard-model prediction of , by fixing the renormalization scheme of the electroweak input parameters.
