Detailed Description

This tool can be used to identify the overlap of a V+jets and V+gamma sample or in fact between most V^n+gamma^m and V^n+gamma^(m-1) samples (e.g.

V+gammagamma vs V+gamma or VV+gamma vs VV). It can either decide whether an event is in the overlap region for fixed cuts on photons and lepton or be used to extract relevant information from the event so that the overlap removal (OR) can be performed at a later stage with a simple 'if' statement.

The OR functions (inOverlap(result), photonPtsOutsideDr(result), or photonPtsOutsideDrs(result)), set the result via reference and return a status code. Usually the tool will take leptons and photons from the current event but this behavior can be overwritten by explicitly setting leptons and photons as additional arguments to the functions.

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::Event 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.

getName()

const std::string & asg::AsgTool::getName ( const void * ptr ) const

inherited

Get the name of an object that is / should be in the event store.

This is a bit of a special one. StoreGateSvc and xAOD::Event both provide ways for getting the std::string name 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::getKey

Parameters

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

Returns

The string name of the object in the store. If not found, an empty string.

Determine whether current event is in overlap region (set via reference).

The overlap region is defined by dR_lepton_photon_cut, photon_pT_cut and many more configurable parameters. Note that the function returns a status code. The first agument is the result, the remaining arguments are optional:

• If null pointers are given for leptons or photons, they will be taken from the event
• One can override this behaviour by manually specifying vectors of lepton/photon
• If lepton or photon origins are given in addition to the lepton four vectors, particles from irrelevant origins (e.g. decays) are filtered out This can be useful when working with derivations which store the origin but not the full truth record

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.
