Abstract: We derive logarithmically enhanced two-loop virtual electroweak correctionsfor arbitrary fermion-scattering processes at the TeV scale. This extendsresults previously obtained for massless fermion scattering to processes thatinvolve also bottom and top quarks. The contributions resulting from soft,collinear, and ultraviolet singularities in the complete electroweak StandardModel are explicitly extracted from two-loop diagrams tonext-to-leading-logarithmic accuracy including all effects associated withsymmetry breaking and Yukawa interactions.
