1Delphes 4 LHCb
2==============
3
4The card "delphes_card_LHCb.tcl" contains a preliminary parametrization of the LHCb detector.
5
6- ParticlePropagator
7
8particles are propagated in a constant B field.
9
10- ChargedHadronMomentumSmearing/ElectronEnergySmearing/MuonMomentumSmearing
11
12charged particles momenta are smeared according to detector resolution
13
14- TrackMerger
15
16charged particles are merged into single collection for simpler future processing
17
18- ImpactParameterSmearing
19
20charged particles transverse IP are smeared according to known LHCb tracking
21performance.
22
23
24- IdentificationMap
25
26This module is a recent addition in order to map particle misidentification rates
27and reconstruction efficiencies.
28
29An example is given in the card but can be expanded if needed.
30
31- ECAL/HCAL
32
33Calorimeter modules are used to parametrize the energy response and angular
34resolution of neutral objects such as photons/neutral hadrons.
35
36- TreeWriter
37
38user specifies here which collections are stored in the output.
39By default tracks, neutral hadrons and photons are stored in this card.
40Tracks contain muons, electrons, and charged hadrons.
