Package RecoMuon/L3MuonProducer

Source code (CVS tag: @) - Administrative privileges

Description

This package provides a module for the HLT to construct Muons from tracker Tracks and L2Muons.

Modules

• L3MuonProducer : Creates the L3MuonProducer framework module that associates L2Muons with Tracker Tracks and performs a global refit of all hits. L3MuonProducer has two member classes which must be configured in the module's configuration file. The first, GlobalMuonTrajectoryBuilder, is the algorithm class which constructs the global muon trajectory. The second, MuonTrackLoader, converts the product of GlobalMuonTrajectoryBuilder into persistant objects and loads them into the Event.

include "RecoMuon/TrackingTools/data/MuonServiceProxy.cff"
include "RecoMuon/TrackingTools/data/MuonTrackLoader.cff"
include "RecoMuon/GlobalTrackingTools/data/GlobalTrajectoryBuilderCommon.cff"

module L3Muons = L3MuonProducer {

    InputTag MuonCollectionLabel = hltL2Muons:UpdatedAtVtx
    
    using MuonServiceProxy
    
    using MuonTrackLoaderForL3

    PSet L3TrajBuilderParameters = {
	using GlobalTrajectoryBuilderCommon
	string KFFitter = "L3MuKFFitter"
	string TransformerOutPropagator = "SmartPropagatorAny"
	string MatcherOutPropagator = "SmartPropagator"

	InputTag l3SeedLabel = "" //hltL3TrajectorySeedFromL2
	InputTag tkTrajLabel = hltL3Trajectory
	
	string TkTrackBuilder = "muonCkfTrajectoryBuilder"
#	string TkTrackBuilder = "muonRSTrajectoryBuilder"
				
    }
}

Inputs:

• MuonCollectionLabel : the TrackCollection of L2Muons

Products:

• reco::Muon Collection: label L3Muons
• reco::Track Collection: label L3Muons
• reco::Track Collection: label L3Muons:L2Seeded -- These are the tracker tracks which are regionally reconstructed from seeds inspired by L2Muons.

Note: For the HLT, the tracker tracks are regionally reconstructed based on the L2Muons. Thus the TrackerSeedGenerator parameters must be configured.
