Delphes 4 LHCb ============== The card "delphes_card_LHCb.tcl" contains a preliminary parametrization of the LHCb detector. - ParticlePropagator particles are propagated in a constant B field. - ChargedHadronMomentumSmearing/ElectronEnergySmearing/MuonMomentumSmearing charged particles momenta are smeared according to detector resolution - TrackMerger charged particles are merged into single collection for simpler future processing - ImpactParameterSmearing charged particles transverse IP are smeared according to known LHCb tracking performance. - IdentificationMap This module is a recent addition in order to map particle misidentification rates and reconstruction efficiencies. An example is given in the card but can be expanded if needed. - ECAL/HCAL Calorimeter modules are used to parametrize the energy response and angular resolution of neutral objects such as photons/neutral hadrons. - TreeWriter user specifies here which collections are stored in the output. By default tracks, neutral hadrons and photons are stored in this card. Tracks contain muons, electrons, and charged hadrons.
