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

It is always delicate to know whether theoretical predictions are visible 
and measurable in a high energy collider experiment due to the complexity 
of the related detectors, data acquisition chain and software. We introduce 
here a new C++ based framework, DELPHES, for fast simulation of a general-
purpose experiment. The simulation includes a tracking system, embedded into 
a magnetic field, calorimetry 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) and outputs observable objects for 
analysis, like missing transverse energy and collections of electrons or jets. 
The simulation of detector response takes into account the detector resolution,
and usual reconstruction algorithms, such as FASTJET. A simplified preselection 
can also be applied on processed data 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. An overview of DELPHES is given 
as well as a few LHC use-cases for illustration.
