Detailed Description

An SubsysReco module to create a set of SQ nodes for the simulation true info.

This module adds the following SQ nodes to the DST top node;

SQMCEvent = info on the primary process like Drell-Yan process (cf. class SQMCEvent)
SQTruthTrackVector = list of true tracks (cf. class SQTrackVector)
SQTruthDimuonVector = list of true dimuons (cf. class SQDimuonVector)

The contents of these nodes are not original but extracted from HepMC::GenEvent, PHG4TruthInfoContainer, etc. Thus you can extract the same or more detailed info when necessary.

The info on the true tracks is stored in HepMC::GenEvent as well, where it is extracted from PHG4TruthInfoContainer in this module. It is because the positions/momenta of tracks at Stations 1 and 3 are accessible only via PHG4TruthInfoContainer. As a side effect, the parent particle type (i.e. PDG ID) of each muon pair is not available now, which is stored only in HepMC::GenEvent. Analyzer should use the (true) invariant mass of muon pair to identify its parent particle type.

Member Function Documentation

int TruthNodeMaker::End ( PHCompositeNode * )

virtual

Called at the end of all processing.

Reimplemented from SubsysReco.

Definition at line 271 of file TruthNodeMaker.cc.

References Fun4AllReturnCodes::EVENT_OK.

int TruthNodeMaker::Init ( PHCompositeNode * )

virtual

Called during initialization. Typically this is where you can book histograms, and e.g. register them to Fun4AllServer (so they can be output to file using Fun4AllServer::dumpHistos() method).

Reimplemented from SubsysReco.

Definition at line 56 of file TruthNodeMaker.cc.

References Fun4AllReturnCodes::EVENT_OK.

int TruthNodeMaker::InitRun ( PHCompositeNode * )

virtual

Called for first event when run number is known. Typically this is where you may want to fetch data from database, because you know the run number.

Reimplemented from SubsysReco.

Definition at line 61 of file TruthNodeMaker.cc.

References Fun4AllReturnCodes::EVENT_OK.

int TruthNodeMaker::process_event ( PHCompositeNode * )

virtual

Called for each event. This is where you do the real work.

Extract the hard process.

Extract the true-track info

Construct the dimuon info

link digi hits to truth tracks

Update truth track pos/mom at station-1/3

optionally, link the rec track to truth track
