Description

Physics analysis

Classes for the physics analysis of the BM@N data: analysis task template, event selection, reconstruction of particle decays (Lambda, hypernuclei), efficiency studies and embedding.

Classes

Class	Description
BmnAnalysisTask	Template of a user analysis task run on DST files by macro/run/run_ana_bmn.C
BmnEventSelector	Pileup event classification of the Run 8 experimental data from the beam counter (BC1) signals and trigger bits; used in run_reco_bmn.C
BmnFunctionAna	Static helper functions of the analysis: magnetic field of a DST file, conversion of the reconstructed data to text

Subdirectories

Directory	Description
decay	Reconstruction of two-body and three-body decays: Lambda, hypernuclei
efficiency	Efficiency of the inner tracker and realistic MC (not compiled)
embedding	Lambda embedding into experimental events (not compiled)
run7	Lambda analysis and trigger efficiency of Run 7 (not compiled)
run8	Trigger efficiency of Run 8

Analysis macros are in macro/physics.

Library

The top-level classes, most of decay and run8 are built into the BmnPhysics library; the ROOT dictionary is defined in PhysicsLinkDef.h. The other subdirectories are kept as sources and are not compiled (see physics/CMakeLists.txt).
