Rare decays of the top quark in the technicolor model with a massless scalar doublet
- 1. Henan Normal Univ., Xinxiang (China). Dept. of Physics
Description
The rare decays t→cV(V = Z, γ, g) induced through loop diagrams are calculated in a minimal Technicolor model (MTC) with a massless weak doublet recently presented by C.D. Carone and H. Georgi. We find that these new contributions can enhance the SM branching fractions by as much as 3-4 orders of magnitude, i.e., B(t→cγ)≅10-9, B(t→cg)≅10-6 for the favorable values of the parameters. It might provide a unique window to detect the virtual effects of technipions in MTC theory
