Final state interaction in kaons decays

S. R. Gevorkyan, A. V. Tarasov, O. O. Voskresenskaya

摘要:

在非相对论量子力学框架下,考虑了K介子衰变到带电和中性π介子对的过程。给出了考虑π介子间强相互作用的两个不同通道的衰变振幅的一般表达式。所开发的方法允许一个估计强相互作用中的任何顺序的条款的贡献,并正确地考虑到在最终状态的π介子之间的电磁相互作用。

英文摘要:

The kaons decays to the pairs of charged and neutral pions are considered in the framework of the non-relativistic quantum mechanics. The general expressions for the decay amplitudes to the two different channels accounting for the strong interaction between pions are obtained. The developed approach allows one to estimate the contribution of terms of any order in strong interaction and correctly takes into account the electromagnetic interaction between the pions in the final state.
