Abstract：
We consider the contributions of the physical top-pions predicted by topcolorassisted technicolor (TC2) models to the single top production via the t-channel process eq→et at the HERA and THERA colliders. We find that the neutral top-pion can generate large contributions to the process ec→et. In most of the parameter space, the production cross section is in the range of 1—6pb. The signals of the neutral top-pion can be studied in the HERA and THERA colliders.
