摘要：

We show that the charged Higgs sector in Weinberg's model for CP violation can cause a large CP violation effect in t --> btaunu(tau). The asymmetry in the partial rate is dominated by contributions such as Z(and gamma)-H+ box diagrams interfering with a (near-resonance) W tree diagram. But far more significant are the asymmetries in the partially integrated rates and in the energy between the tau+ and the tau-. These stem from (near-resonance) W-tree-H+-tree interference.
