论文摘要
我们开发了EventMover，这是一个可区分的Parton淋浴事件生成器。该工具生成高和可变的长度散射事件，可以使用模拟导数移动，以更改定义强耦合常数的比例$λ_\ mathrm {qcd} $，而无需引入样本之间的统计变化。为了证明事件的潜力，我们将模拟的输出与$ e^+e^ - $数据进行比较，以显示如何将$λ__\ mathrm {qcd} $与仅单个事件样本拟合。这是迈向粒子和核物理的完全可区分事件发生器的关键步骤。
We develop EventMover, a differentiable parton shower event generator. This tool generates high- and variable-length scattering events that can be moved with simulation derivatives to change the value of the scale $Λ_\mathrm{QCD}$ defining the strong coupling constant, without introducing statistical variations between samples. To demonstrate the potential for EventMover, we compare the output of the simulation with $e^+e^-$ data to show how one could fit $Λ_\mathrm{QCD}$ with only a single event sample. This is a critical step towards a fully differentiable event generator for particle and nuclear physics.
