Delphes,一个通用对撞机实验快速模拟框架

Delphes, a framework for fast simulation of a generic collider experiment

S. Ovyn, X. Rouby, V. Lemaitre

摘要:

本文提出了一种新的C++框架,DELPHES,执行一个快速的多用途探测器响应模拟。模拟包括一个跟踪系统,嵌入到一个磁场,量热计和μ子系统,并可能非常向前探测器沿光束线排列。该框架与标准文件格式(例如Les Houches Event File或HepMC)接口,并输出可用于专门分析的可观测量,如孤立轻子,缺失的横向能量和射流集合。探测器响应的模拟考虑了磁场的影响、量热计的粒度和子探测器分辨率。简化的预选也可以应用于触发器模拟的已处理事件。非常前向散射粒子的检测依赖于HECTOR软件在光束线中的传输。最后,FROG 2D/3D事件显示用于碰撞最终状态的可视化。

英文摘要:

This paper presents a new C++ framework, DELPHES, performing a fast multipurpose detector response simulation. The simulation includes a tracking system, embedded into a magnetic field, calorimeters and a muon system, and possible very forward detectors arranged along the beamline. The framework is interfaced to standard file formats (e.g. Les Houches Event File or HepMC) and outputs observables such as isolated leptons, missing transverse energy and collection of jets which can be used for dedicated analyses. The simulation of the detector response takes into account the effect of magnetic field, the granularity of the calorimeters and subdetector resolutions. A simplified preselection can also be applied on processed events for trigger emulation. Detection of very forward scattered particles relies on the transport in beamlines with the HECTOR software. Finally, the FROG 2D/3D event display is used for visualisation of the collision final states.
