The two-particle momentum correlation function of a K^{-}p pair from high-energy nuclear collisions is evaluated in the K[over ¯]N-πΣ-πΛ coupled-channel framework. The effects of all coupled channels together with the Coulomb potential and the threshold energy difference between K^{-}p and K[over ¯]^{0}n are treated completely for the first time. Realistic potentials based on the chiral SU(3) dynamics are used which fit the available scattering data. The recently measured correlation function is found to be well reproduced by allowing variations of the source size and the relative weight of the source function of πΣ with respect to that of K[over ¯]N. The predicted K^{-}p correlation function from larger systems indicates that the investigation of its source size dependence is useful in providing further constraints in the study of the K[over ¯]N interaction.

高能核碰撞和手性SU（3）动力学的K ^ {-} p相关函数。

在K [N]-π-Σ-π耦合通道框架中，评估了高能核碰撞产生的K ^ {-} p对的两粒子动量相关函数。所有耦合通道的影响连同库仑电势以及K ^ {-} p和K [over] ^ {0} n之间的阈值能量差都将首次得到完全处理。使用基于手性SU（3）动力学的现实势能，该势能适合可用的散射数据。发现通过允许源大小和源函数相对于K [N]的变化的相对权重的变化，可以很好地再现最近测量的相关函数。
