|
|---|
| 3 |
|
|---|
| [42f8e78] | 4 | The card "delphes_card_LHCb.tcl" contains a preliminary parametrization of the LHCb detector.

| 6 | - ParticlePropagator
|
|---|
| 7 |
|
|---|
| 8 | particles are propagated in a constant B field.
|

| 10 | - ChargedHadronMomentumSmearing/ElectronEnergySmearing/MuonMomentumSmearing
|
|---|
| 11 |
|
|---|
| 12 | charged particles momenta are smeared according to detector resolution
|
|---|
| 13 |
|

| 14 | - TrackMerger
|
|---|
| 15 |
|
|---|
| 16 | charged particles are merged into single collection for simpler future processing
|

| 18 | - ImpactParameterSmearing
|
|---|
| 19 |
|
|---|
| 20 | charged particles transverse IP are smeared according to known LHCb tracking

| 24 | - IdentificationMap
|
|---|
| 25 |
|
|---|
| [42f8e78] | 26 | This module is a recent addition in order to map particle misidentification rates
|
|---|
| [66b590f] | 27 | and reconstruction efficiencies.
|
|---|
| 28 |
|
|---|
| 29 | An example is given in the card but can be expanded if needed.

|
|---|
| 31 | - ECAL/HCAL
|
|---|
| 32 |
|
|---|
| 33 | Calorimeter modules are used to parametrize the energy response and angular
|
|---|
| 34 | resolution of neutral objects such as photons/neutral hadrons.
|
|---|
| 35 |
|
|---|
| 36 | - TreeWriter
|
|---|
| 37 |
|
|---|
| 38 | user specifies here which collections are stored in the output.
|
|---|
| 39 | By default tracks, neutral hadrons and photons are stored in this card.
|
|---|
| 40 | Tracks contain muons, electrons, and charged hadrons.
