Description
Knowing whether theoretical predictions are visible and measurable in
a High Energy experiment is always delicate, due to the complexity of the
related detectors, DAQ chain and software. We introduce here a new
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 format from event
generators (e.g. Les Houches Event File) and outputs observable analysis
data objects, like missing transverse energy and collections of electrons
or jets.
The simulation of the detector response takes into account the
detector resolution, and usual reconstruction algorithms for complex objects, like
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 use-cases for
illustration.
