IDTrackSel

Simple wrappers around ATLAS track selection tools (InDetTrackSelectionTool and TrackVertexAssociationTool). Tested in R21.2 and (hopefully) backwards-compatible to R20.7.

Setup

In R21, these have been tested in AnalysisBase/21.2.46+ but likely work with earlier releases.

You must add a sparse checkout of athena and include the InDetTrackSystematicsTools package locally.

In R20.7, try something like:

setupATLAS
rcSetup Base,2.4.28
git clone https://github.com/mattleblanc/IDTrackSel.git
rc build

Usage

These wrappers are meant for use with xAODAnaHelpers. To use it, you could specify part of a config such as ...

c.setalg("InDetTrackSelectionToolAlgo", {
    "m_debug": False,
    "m_name": "InDetTrackSelectionToolAlgo",
    "m_inputTrackContainer": "InDetTrackParticles",
    "m_outputTrackContainer": "SelectedTrackParticles",
    "m_CutLevel": "Loose"
})

c.setalg("TightTrackVertexAssociationToolAlgo", {
        "m_debug": False,
        "m_name": "TightTrackVertexAssociationToolAlgo",
        "m_inputTrackContainer": "SelectedTrackParticles",
        "m_outputTrackContainer": "PVTrackParticles",
        "m_dzSinTheta_cut": 3,
        "m_doPV": True
})

c.setalg("TreeAlgo", {"m_debug": False,
                      "m_name": "rcRes",
                      "m_trackParticlesContainerName": "PVTrackParticles",
                      "m_trackParticlesDetailStr": "kinematic trackpars numbers vertex",
                    })

Systematics

Algorithms are included which provide easy implementations of the recommended tracking systematics in R21:
