Delphes

A framework for fast simulation of a generic collider experiment

Delphes is a C++ framework, 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.

Community and support

Delphes is now moving to community-based developement. A forum is already open to authenticated members in order to exchange on issues and features requests. The branches of the svn repository are open to users who would like to participate. If you are interested, register first and then contact the suport team via cp3-delphes@… to be granted svn access.

Quick start

Beginners will find help in the Documentation and the FAQ.

Downloads

Production version 2.0.3:

  • b-tagging now based on b-quark content (thanks to A.Mertens)
  • track isolation bugfix (Ticket #61, thanks to Sourav Mandal)

Production version 2.0.2:

  • Compatible with HepMC 2.05 and 2.06
  • Solved: some tracks were ignored in the computation of ptiso (thanks to Sourav Mandal)
  • Solved: Memory leak preventing to load many events using HepMC (thanks to Sourav Mandal)
  • Solved bug in root genparticles branches when reading HepMC files (thanks to Nadja Strobbe)
  • Solved bug in b-tagging (thanks to Alexandre Mertens)
  • Solved bug in !Examples/Analysis_Ex.cpp (thanks to hashemi.mj)
  • Solved bug in ExRootAnalysis (thanks to Pavel Demin and lessa.a.p)
  • Includes Frog 3.0 (You should never need a FROG-free version anymore)
