All these calculation are done in ’t Hooft gauge. Normally, the results are one-loop <span>$\\overline{\\mathrm{DR}}$</span> masses and mixing matrices. For further calculations, the mixing matrices corresponding to an external momentum equal to the heaviest mass eigenstate is taken. However, for SM particles the pole masses are used in the decays as well as in the output.
