Signatures of the neutral top-pion in eγ collisions
Abstract
We calculate the contributions of the neutral top-pion πt0 to the process e-γ e-tc in the framework of topcolor-assisted technicolor(TC2) models and discuss the possible of detecting πt0 at the high energy linear e+e- collider(LC). Our results show that πt0 can give significant contributions to this process. With reasonable values of the parameters in TC2 models, the cross section σ can reach 0.19 fb which may be detected at the eγ collisions based on the future LC experiments.
