摘要：

Using chiral low energy theorems and elastic unitarity assumption, the tau --> pi K nu decay is investigated. The vector and scalar pi K form factors are calculated. It is found that the pi K spectrum is dominated by the K* resonance, By measuring the forward-backward asymmetry, it is shown that the S wave pi K phase shift can be determined near the K* resonance region. The calculated branching ratio and resonance parameters are in good agreement with experiments.
