$H_{TC}{\Pi }^0$ and ${\Pi }^{+}{\Pi }^{-}$ pair productions at the planned $e^{+}{e}^{-}$ colliders in the topcolor-assisted technicolor model

Abstract

The top-pions(${\Pi }^{0,\pm }$) and the top-Higgs($H_{TC}$) are the typical particles predicted by the topcolor-assisted technicolor (TC2) model and the observation of these particles can be regarded as the direct evidence of the TC2 model. In this paper, we study two pair production processes of these new particles, i.e., $e^{+}{e}^{-}\to H_{TC}{\Pi }^0$ and $e^{+}{e}^{-}\to {\Pi }^{+}{\Pi }^{-}$. The results show that the production rates are at the level of serval fb for $e^{+}{e}^{-}\to H_{TC}{\Pi }^0$ and tens fb for $e^{+}{e}^{-}\to {\Pi }^{+}{\Pi }^{-}$. These processes can produce the adequate distinct multi-jet final states and the SM background can be efficiently reduced. So, with the high luminosity at the planned linear colliders, the top-pions and top-Higgs can be observable via these two pair production processes without double.
