通过考虑荷电-电流准弹性相互作用的全运动学相空间内的模型扩展，量化了由于核效应而导致的、和横截面比错误建模的可能性。然后，它的影响被传播到基于Hyper-K和实验的模拟实验构型。虽然确认了理论模型之间的显著差异，但发现这些差异主要存在于相空间区域，这些区域只贡献了通量积分截面的一小部分。总体而言，对于Hyper-K和，分别发现了振荡通量平均截面比的系统不确定性。
The potential for mismodeling of,, andcross-section ratios due to nuclear effects is quantified by considering model spread within the full kinematic phase space for charged-current quasielastic interactions. Its impact is then propagated to simulated experimental configurations based on the Hyper-K andexperiments. Although significant discrepancies between theoretical models is confirmed, it is found that these largely lie in regions of phase space that contribute only a very small portion of the flux-integrated cross sections. Overall, a systematic uncertainty on the oscillated flux-averagedcross-section ratio is found to beandfor Hyper-K and, respectively.
