Abstract

In the framework of topcolor-assisted technicolor(TC2) models, we calculate the contributions of flavor changing scalar couplings involved the neutral top-pion π_t⁰ and top-Higgs h_t⁰ to the branching ratio B_r(t\longrightarrow cg). We find that the value of B_r(t\longrightarrow cg) can reach 1×10^-3 with reasonable values of the parameters in TC2 models, which may be testable in the future experiments.
