   <hidden TTP05-17  Two-Loop Electroweak Logarithms in Four-Fermion Processes at High Energy > We present the complete analytical result for the two-loop
 logarithmically enhanced contributions to the high energy asymptotic
 behavior of the vector form factor and the four-fermion cross section
 in a spontaneously broken SU(2) gauge model. On the basis of this
 result we derive the dominant two-loop electroweak corrections to the
 neutral current four-fermion processes at high energies. Previously
 neglected effects of the gauge boson mass difference are included
 through the next-to-next-to-leading logarithmic approximation.
