| Abstract: | TC(technicolor) corrections to tt? production in high-energy photon-photon collision are calculated in the topcolor-assisted multiscale technicolor(TOPCMTC) model. We find that the contribution of the technipions to the production cross section of the process γγ → tt? is very small. The relative corrections to the production cross section mainly come from the top-pions, which may be observable at future e + e -. linear collider. |
