Detailed Description

James Frost
November 2014.

Updated for Run 3 by Bill Balunas March 2020

Tool to calculate the jet vertex tag (JVT) JVT is a float per jet

The JVT likelihood is parameterised in terms of: RPT: ratio of the primary vertex track sum to the jet pT JVFCorr: a corrected JVF calculation accounting for the number of PU tracks in the event.

Calculation requires three main types of information

1. Vertex container for the event (from evtStore), with respect to which the JVT track sums
2. Tracks associated to each of the input jet (in the jet aux store)
3. Track vertex association object (from evtStore)
4. The track container needed for PU track counting
5. The ID track selector tool to provide an input track selection.
6. An input file with the JVT likelihood stored as a 2D histogram.

Using this information, the procedure can be broken into three main steps:

1. Count the total number of pileup tracks
2. Per jet: Get track pT sums needed for JVFCorr and RpT
3. Use JVT likelihood to get JVT value

Attributes added (each is a float per jet):

1. Jvt - the JVTLikelihood value for the jet. This is parameterised in terms of:
2. JvtRpt - the ratio of the PV track pT sum to the jet pT
3. JvtJvfcorr - a corrected Jvf quantity that corrects for the number of pileup tracks in an event.

Properties: JetContainer - name of the jet container VertexContainer - name of the vertex container TrackParticleContainer - name of the track container AssociatedTracks - name for attribute holding the list of associated tracks TrackVertexAssociation - name for the container holding the track-vertex associations TrackSelector - tool to select tracks (none ==> no selection) JVTFileName - ROOT Filename containing JVT likelihood histogram JVTLikelihoodHistName - JVT Likelihood histogram name JVTName - name for the 3 JVT attributes (default is "JVT") K_JVFCorrScale - the scale factor for pileup tracks in the JVFCorr calculation (default is 0.01) Z0Cut - Z0 value (in mm) within which tracks associated to no vertex may be assigned to the primary vertex (default is 3.) PUTrkPtCut - the track pT (in MeV) below which tracks associated to no vertex may be assigned to the primary vertex (default is 30000.)

getKey()

SG::sgkey_t asg::AsgTool::getKey ( const void * ptr ) const

inherited

Get the (hashed) key of an object that is in the event store.

This is a bit of a special one. StoreGateSvc and xAOD::TEvent both provide ways for getting the SG::sgkey_t key for an object that is in the store, based on a bare pointer. But they provide different interfaces for doing so.

In order to allow tools to efficiently perform this operation, they can use this helper function.

See also

asg::AsgTool::getName

Parameters

ptr	The bare pointer to the object that the event store should know about

Returns

The hashed key of the object in the store. If not found, an invalid (zero) key.

sysInitialize()

virtual StatusCode AthCommonDataStore< AthCommonMsg< AlgTool > >::sysInitialize ( )

overridevirtualinherited

Perform system initialization for an algorithm.

We override this to declare all the elements of handle key arrays at the end of initialization. See comments on updateVHKA.

Reimplemented in asg::AsgMetadataTool, AthCheckedComponent< AthAlgTool >, AthCheckedComponent<::AthAlgTool >, and DerivationFramework::CfAthAlgTool.

sysStart()

virtual StatusCode AthCommonDataStore< AthCommonMsg< AlgTool > >::sysStart ( )

overridevirtualinherited

Handle START transition.

We override this in order to make sure that conditions handle keys can cache a pointer to the conditions container.

updateJvt()

float JetVertexTaggerTool::updateJvt ( const xAOD::Jet & jet ) const

overridevirtual

Calculate the updated JVT.

jet - jet for which JVT is updated The new value for JVT is returned.

Implements IJetUpdateJvt.
