The version 3.0 of the DELPHES fast-simulation is presented. The goal of
DELPHES is to allow the simulation of a multipurpose detector for
phenomenological studies. The simulation includes a track propagation system
embedded in a magnetic field, electromagnetic and hadron calorimeters, and a
muon identification system. Physics objects that can be used for data analysis
are then reconstructed from the simulated detector response. These include
tracks and calorimeter deposits and high level objects such as isolated
electrons, jets, taus, and missing energy. The new modular approach allows for
greater flexibility in the design of the simulation and reconstruction
sequence. New features such as the particle-flow reconstruction approach,
crucial in the first years of the LHC, and pile-up simulation and mitigation,
which is needed for the simulation of the LHC detectors in the near future,
have also been implemented. The DELPHES framework is not meant to be used for
advanced detector studies, for which more accurate tools are needed. Although
some aspects of DELPHES are hadron collider specific, it is flexible enough to
be adapted to the needs of electron-positron collider experiments.

DELPHES 3.0 是一个快速模拟工具，具有模拟探测器响应的能力，旨在为各种表观研究提供多功能探测器的模拟。可以从模拟探测器响应中重建各种物理对象，包括跟踪、块状量以及高级对象，如孤立电子、喷注、tau 子和缺失能量。

DELPHES 3, A modular framework for fast simulation of a generic collider  experiment

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.

DELPHES 是基于 C++ 的新型框架，提供了快速的多用途探测器响应模拟，包括磁场中的跟踪系统、能量计、μ 子系统以及可能沿着射线线排列的前向探测器；模拟考虑了磁场，探测器的晶格和子探测器分辨率的影响，可应用于专门的分析，输出包括孤立电子、跨越能量丢失和喷注等可观测物理量。
