| Abstract: | The neutral top-pion πt0 can couple to the gluons and the photons through the top quark triangle-loop. we calculate the corrections of the neutral top-pion πt0 to the tt production cross section in topcolor-assisted multiscale walking technicolor model. We find that, for a heavy neutral top-pion, the corrections are quite significant. For mt = 175 GeV, 5 GeV ≤ mt1 ≤ 20 GeV and Mπt = 350 GeV, the relative correction Δσ/σ0 is larger than 10% which might be observed at a high-luminosity Tevatron. We further estimate the production cross section of πt0 at the NLC experiment. We find that the production rate is significantly large. The neutral top-pion πt0 may be detected in future e+e- linear collider experiments. |
