The flavor-changing rare top decays in topcolor-assisted technicolor theory
In the framework of topcolor-assisted technicolor (TC2) theory, we calculate
the contributions of the scalars(the neutral top-pion and the
top-Higgs ) to the flavor-changing rare top decays (V=
W, g, or Z). Our results show that can enhance the
standard model by several orders of
magnitude for most of the parameter space. The peak of the branching ratio
resonance emerges when the top-Higgs mass is between and . The
branching ratio can reach in the narrow range.Comment: Latex file, 11pages, 2 eps figure
