摘要：The leptonic decay B−→τ− ¯ ντ and the semileptonic decays B→D(∗)τ− ¯ ντ provide opportunities for testing the Standard Model and searching for new physics. Extended models including a charged Higgs boson are sensitive to these decays. In this report, recent results obtained at the B factories are introduced. Several results show the discrepancies from the expectations from the Standard Model.
