Abstract
We study dark sector production in electromagnetic (EM) cascades. This problem requires accurate simulations of Standard Model (SM) and dark sector processes, both of which impact angular and energy distributions of emitted particles that ultimately determine flux predictions in a downstream detector. We describe the minimal set of QED processes which must be included to faithfully reproduce a SM cascade, and identify a universal algorithm to generate a dark sector flux given a Monte-Carlo simulation of a SM shower. We provide a new tool, , which simulates EM cascades with associated dark vector production, and compare it against existing literature and “off the shelf” tools. The signal predictions at downstream detectors can strongly depend on the nontrivial interplay (and modelling) of SM and dark sector processes, in particular multiple Coulomb scattering and positron annihilation. We comment on potential impacts of these effects for realistic experimental setups.
我们研究电磁(EM)级联中暗扇区的产生。这个问题需要精确模拟标准模型(SM)和暗扇过程,两者都会影响发射粒子的角度和能量分布,最终决定下游探测器的通量预测。我们描述了为忠实再现 SM 级联而必须包含的最小 QED 过程集,并确定了在对 SM 阵雨进行蒙特卡洛模拟的情况下生成暗扇区通量的通用算法。我们提供了一种新工具,它可以模拟电磁级联和相关暗矢量的产生,并将其与现有文献和 "现成 "工具进行比较。下游探测器的信号预测在很大程度上取决于 SM 和暗部门过程的非微观相互作用(和建模),特别是多重库仑散射和正电子湮灭。我们评论了这些效应对现实实验装置的潜在影响。
