Özet

We discuss the degree of spin polarization of single top quarks produced via the Wg fusion process in ep collisions at DESY TESLA+HERAp and CERN CLIC+LHC energies roots=1.6 and 5.3 TeV. A description of how to combine the cross sections of e(+)b-->t (nu) over bar and e(+)g-->tb (nu) over bar processes is given. The e(+)-beam direction is taken to be the favorite top quark spin decomposition axis in its rest frame and it is found to be comparable with the ones in pp collisions. It is argued that theoretical simplicity and experimental clearness are the advantage of ep collisions.
