论文摘要
通常根据部分波和相应的耦合通道相移和混合角来分析NN散射问题，但是可用的实验会引起与量子数不同的相应通道之间的相关性。基于Granada-2013数据库，我们分析了这些相关性的含义和影响，这些相关关系既考虑了统计统计数据，反映了主要实验数据不确定性的统计数据，以及系统的统计数据，以代表3fm低于3fm的距离的潜在核力量表现出歧义的系统。我们还思考通过直接拟合固定核电位的含义，这是由于从实验数据中推断出的全壁部分波分析（PWA）所产生的相移。
The NN scattering problem is usually analyzed in terms of partial waves and the corresponding coupled channel phase-shifts and mixing angles, but the available experiments induce correlations amongst the corresponding channels with different quantum numbers. Based on the Granada-2013 database we analyze the meaning and impact of those correlations taking into account both the purely statistical ones reflecting the primary experimental data uncertainties as well as the systematic ones exhibiting the ambiguities in the form of the potential representing the unknown nuclear force for distances below 3fm. We also ponder on the implications of fixing nuclear potentials by direct fits to the phase-shifts stemming from a full fledged partial wave analysis (PWA) inferred from experimental data.
