Description

CA track finder (CBM L1)

The Cellular Automaton (CA) track finder of the CBM experiment (L1 reconstruction package) adapted for the BM@N inner tracker. It finds tracks in the VSP, Forward Silicon and GEM hits converted into CbmStsHit objects by BmnToCbmHitConverter (detectors/sts) and fits them with the Kalman filter of the KF package. In run_reco_bmn.C it is run by CbmStsFindTracks with the CbmL1StsTrackFinder algorithm (L1 tracking mode, StsTrack branch).

Classes

Class / file	Description
CbmL1	Main task of the L1 reconstruction: reads the geometry, the field and the hits, runs L1Algo and the performance analysis
CbmStsFindTracks	Task running a track finder (CbmStsTrackFinder implementation) and storing the CbmStsTrack objects
CbmStsFindTracksQa	QA of the track finding
CbmL1Track, CbmL1TrackPar	Reconstructed L1 track and its parameters
CbmL1Vtx	Vertex used by L1
CbmL1StsHit, CbmL1MCPoint, CbmL1MCTrack	Hits with the MC matching, MC points and MC tracks used in the performance analysis
CbmL1ParticlesFinder, CbmL1PartEfficiencies	Search for short-lived particles (Lambda, K0) and their efficiencies
CbmL1Def.h, CbmL1Constants.h	Common definitions (SIMD vector types) and performance constants

Subdirectories

Directory	Description
L1Algo	Core of the CA track finder: triplets, track candidates, track fit and extension
OffLineInterface	Interface of L1 to the CbmStsTrackFinder framework
ParticleFinder	Track fitter and MC particles of the L1 particle finder
vectors	SIMD vector classes used by L1
utils	Macros to draw the L1 histograms and the field approximation
