Abstract

We study single-top production at linear lepton colliders with s=0.5, 1, and 3 TeV. A preliminary analysis shows that despite the large tt¯ background at s=0.5 and 1 TeV it is possible to obtain a good sensitivity to the tbW vertex, even more so at 3 TeV when single top becomes the dominant mode of production. Concerning the four-dimension six operators involved, two of them simultaneously generate ttZ couplings and their sensitivity decreases with energy. The opposite is true for the other two operators. Single-top production at these machines is also useful to probe charged-current four-fermion operators eνbt, some of which are related to tbW operators through the equations of motion.
