论文摘要
我们基于现代的Pion-Kaon $ p $ - 波相移输入，在所有电荷通道中提供了反应振幅$γk\至kπ$的分散理论表示。跨通道的奇异性是尽可能从现象学中固定的。我们证明了如何将$ k^*（892）$共振的低能量定理和辐射耦合匹配，从而提供了独立的模型框架，以供将来分析高精度Kaon Primakoff数据。
We provide a dispersion-theoretical representation of the reaction amplitudes $γK\to K π$ in all charge channels, based on modern pion-kaon $P$-wave phase shift input. Crossed-channel singularities are fixed from phenomenology as far as possible. We demonstrate how the subtraction constants can be matched to a low-energy theorem and radiative couplings of the $K^*(892)$ resonances, thereby providing a model-independent framework for future analyses of high-precision kaon Primakoff data.
