摘要
In the framework of top-color assisted technicolor (TC2) theory, we study the four decay processes of charged top-pion, i.e., . The decay branching ratio of these modes are calculated. The results show that the main decay channels of charged top-pion are the tree level modes: and . Light is easier to be detected than heavy one at future coliders. So, the study provides us with some useful informations to search for charged top-pion.
