17It is always delicate to know whether theoretical predictions are visible
18and measurable in a high energy collider experiment due to the complexity
19of the related detectors, data acquisition chain and software. We introduce
20here a new C++ based framework, DELPHES, for fast simulation of a general-
21purpose experiment. The simulation includes a tracking system, embedded into
22a magnetic field, calorimetry and a muon system, and possible very forward
23detectors arranged along the beamline. The framework is interfaced to standard
24file formats (e.g. Les Houches Event File) and outputs observable objects for
25analysis, like missing transverse energy and collections of electrons or jets.
26The simulation of detector response takes into account the detector resolution,
27and usual reconstruction algorithms, such as FASTJET. A simplified preselection
28can also be applied on processed data for trigger emulation. Detection of
29very forward scattered particles relies on the transport in beamlines with
30the HECTOR software. Finally, the FROG 2D/3D event display is used for
31visualisation of the collision final states. An overview of DELPHES is given
32as well as a few LHC use-cases for illustration.
