Abstract
We study the single top quark production process in various kinds of technicolor models in high energy positron photon collisions at the future electron positron linear colliders. It is shown that if there is certain charged pseudo Goldstone boson (PGB) coupling to t(anti-b), the t(anti-b)-channel PGB contribution is dominant, but the situation is quite different from that in the neutral channel, t(anti-t) production in photon photon collisions, due to the destructive nature of different amplitudes. At the DESY limear collider TESLA, the event rates in models with t(anti-b)-channel PGB contributions, such as the top-color-assisted technicolor model, etc. are experimentally measurable. This process provides a feasible test of technicolor models with t(abti-b)-channel PGB contributions.
