英文摘要：

TC2 model is one of interesting new physics models and there exit some new flavor-changing couplings in this model. This research explores the contribution of the TC2 model to the tb^- process. The research shows that the TC2 model makes great contribution to the process. With the running of LHC,it is hoped that the clue of the TC2 model can be found via the process and such process can provide the evidence to test the TC2 model.
