论文摘要
我们总结了分散关系在确定低能$πk$交互作用中的应用。特别是，我们介绍了对$πk\ toπk$和$ππ\ rightarrow k \ bar k $ Channels的完整研究的最新分散分析。首先，我们总结了我们的方法，我们通过使用几个分散关系家族来研究两个渠道，并提出最相关的部分波浪。然后，我们将色散形式主义应用于阈值区域，在那里我们提取许多不同的低能参数。
We summarize the application of dispersion relations for the determination of low energy $πK$ interactions. In particular, we present our recent dispersive analyses for the complete study of both $πK\to πK$ and $ππ\rightarrow K \bar K$ channels. First, we summarize our approach, we study both channels by using several families of dispersion relations and present the most relevant partial waves. Then we apply the dispersive formalism to the threshold region, where we extract many different low-energy parameters.
