The study of the charged top-pion decay processes

Abstract

In the framework of top-color assisted technicolor(TC2) theory, we study the four decay processes of charged top-pion, i.e., ${\Pi }_t^{+}\to t\bar{b}$, ${\Pi }_t^{+}\to c\bar{b}$, ${\Pi }_t^{+}\to W^{+}\gamma$, ${\Pi }_t^{+}\to W^{+}{Z}^0$, 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: ${\Pi }_t^{+}\to t\bar{b}$ and ${\Pi }_t^{+}\to c\bar{b}$. Light ${\Pi }_t^{+}$ is easier to be detected than heavy one at future coliders. So, the study provides us some useful information to search for charged top-pion.
