摘要:

本文将费米-沃森定理推广到两个不同质量耦合通道的情形,并应用于$K_{e4}$衰变的末态相互作用。所考虑的影响的相位上的$ππ$散射的估计和示出,它可以是至关重要的散射长度提取$K_{e4}$衰变的实验数据。

英文摘要:

The Fermi-Watson theorem is generalized to the case of two coupled channels with different masses and applied to final state interaction in $K_{e4}$ decays. The impact of considered effect on the phase of the $ππ$ scattering is estimated and shown that it can be crucial for scattering lengths extraction from experimental data on $K_{e4}$ decays.
