摘要：

The tau-polarization has a fairly significant effect on the charged Higgs signature at the hadron colliders. It is best seen in the tau-mu channel followed by the pionic decay of tau. The average p(T) of the pion originating from the W boson is only about half of that originating from a charged Higgs of comparable mass. This can be used to improve the signal/background ratio by a factor of approximately 3. It can also serve as an independent signature for the charged Higgs boson.
