  • 开源工具便于物理学家与深度学习研究者协作开发新型粒子识别方法。

深度学习在核物理与粒子物理实验中的应用推动了模拟与重建流程的进步。然而,传统模拟框架如Geant4在切伦科夫探测器仿真中仍存在计算瓶颈,尤其在复杂几何结构和反射表面下的光子传输模拟。为此,我们提出一个面向未来电子-离子对撞机(EIC)高性能切伦科夫探测器(hpDIRC)的开放、独立的快速仿真工具,专用于内部反射切伦科夫光检测(DIRC)。该框架集成一系列生成模型,可显著加速粒子识别(PID)任务,提供可扩展的GPU加速替代方案。设计注重易用性,使深度学习研究人员与物理学家无需依赖复杂的传统模拟系统,即可按需生成大规模高保真数据集,支持新型深度学习驱动的PID方法的研发与评测。该快速仿真流程为依赖海量模拟样本的EIC全局粒子识别策略提供了关键支撑。

原文摘要 · Abstract (English)

The integration of Deep Learning (DL) into experimental nuclear and particle physics has driven significant progress in simulation and reconstruction workflows. However, traditional simulation frameworks such as Geant4 remain computationally intensive, especially for Cherenkov detectors, where simulating optical photon transport through complex geometries and reflective surfaces introduces a major bottleneck. To address this, we present an open, standalone fast simulation tool for Detection of Internally Reflected Cherenkov Light (DIRC) detectors, with a focus on the High-Performance DIRC (hpDIRC) at the future Electron-Ion Collider (EIC). Our framework incorporates a suite of generative models tailored to accelerate particle identification (PID) tasks by offering a scalable, GPU-accelerated alternative to full Geant4-based simulations. Designed with accessibility in mind, our simulation package enables both DL researchers and physicists to efficiently generate high-fidelity large-scale datasets on demand, without relying on complex traditional simulation stacks. This flexibility supports the development and benchmarking of novel DL-driven PID methods. Moreover, this fast simulation pipeline represents a critical step toward enabling EIC-wide PID strategies that depend on virtually unlimited simulated samples, spanning the full acceptance of the hpDIRC.
