论文摘要
我们提出了一个新颖的Lepton-Nucleus事件生成器：Achilles，芝加哥Lepton事件模拟器。发电机将原子核中黑德子传播的主要相互作用分配，这允许大量模块化，从而促进进一步的改进和与现有代码的接口。我们验证了我们的发电机在准循环状态下的高质量电子碳散射数据，包括最近对现有数据的CLAS/E4V重新分析。我们在包容性和独家分布中都发现了良好的共识。通过改变对整个核中敲除核的传播的假设，我们估计了理论不确定性的组成部分。我们还提出了新颖的可观察物，可以进一步测试Lepton-Nucleus散射模型。阿喀琉斯很容易扩展以产生中微子核散射事件。
We present a novel lepton-nucleus event generator: ACHILLES, A CHIcagoLand Lepton Event Simulator. The generator factorizes the primary interaction from the propagation of hadrons in the nucleus, which allows for a great deal of modularity, facilitating further improvements and interfaces with existing codes. We validate our generator against high quality electron-carbon scattering data in the quasielastic regime, including the recent CLAS/e4v reanalysis of existing data. We find good agreement in both inclusive and exclusive distributions. By varying the assumptions on the propagation of knocked out nucleons throughout the nucleus, we estimate a component of theoretical uncertainties. We also propose novel observables that will allow for further testing of lepton-nucleus scattering models. ACHILLES is readily extendable to generate neutrino-nucleus scattering events.
