Accessible as member functions of HltDecReport

Physics and non-physics trigger lines and Hltx Global reports.

Among physics lines post-scaled L0xxx pass-through-Hlt1 lines.

(from Gerhard: errorBits=2 in this release means executions of this line took a long time)

The value of numberOfCandidates() saturates at 15 (means 15 or more candidates)

(8)

HltDecReport – executionStage()

• Meaning of execuationStage() values in HltDecReport :

0 initial (did not pass prescale)

1 passed prescale (did not pass L0 seeding) 2 passed seeding (did not pass filter-0)

3 passed filter-0 (did not pass filter-1) 4 passed filter-1 (did not pass filter-2) 5 passed filter-2 (did not pass filter-last) 6 passed filter-last (did not pass postscale) 7 passed postscale [ decision is set to true ]

• More bits were added to this field – the meaning of the

values is likely to change in the future release (max value

255)

Accessing decisions via TriggerTisTos tool

• In addition to getting decision() of individual trigger lines you can also check logical-OR of decisions between many lines

– Particularly easy if you can address all trigger lines of interest with a wild character matching:

#include "Kernel/

#include "Kernel/ITriggerTisTos.hITriggerTisTos.hITriggerTisTos.hITriggerTisTos.h""""

ITriggerTisTos ITriggerTisTos ITriggerTisTos

– You can also specify a list of trigger names to be OR-ed explicitly:

TIS and TOS classifications

• Signal – off-line selected particle (simple or composite) e.g.

B

_d

→ µµK, K → Kπ candidate

• Can classify each trigger decision (individual trigger line or OR between many lines) as:

– TOS – Trigger On Signal

– TIS – Trigger Independent of Signal

• Four types of trigger decisions:

– Neither TOS nor TIS (called “TOB”) – TOS but not TIS

– TIS but not TOS

– TOS and TIS at the same time

• Classification useful for:

– Trigger optimization (e.g. TOB events are undesired) – Trigger monitoring

– Determination of trigger efficiencies and trigger biases in physics analysis from data themselves

Classified trigger decisions

• decision() decision() decision() decision() does not depend on the signal !

• The Trigger Input [here "Hlt2Decision" "Hlt2Decision" "Hlt2Decision" "Hlt2Decision" ] can be specified in other ways shown on slide 9

• Also the Offline Input [here Particle signal Particle signal Particle signal Particle signal ] can be specified ahead of the m_tisTos m_tisTos- m_tisTos m_tisTos - - -> > > >triggerTisTos triggerTisTos triggerTisTos triggerTisTos call, at once by setOfflineInput(signal setOfflineInput(signal setOfflineInput(signal setOfflineInput(signal) ) ) )

Access to candidates selected by triggers

• HltSelReports HltSelReports HltSelReports HltSelReports have information about selected candidates (Tracks, Vertices, Particles, …)

• I don’t expect many users will want to access

HltSelReports HltSelReports HltSelReports

HltSelReports directly

– if you do, this container has analogous structure to HltDecReports HltDecReports HltDecReports HltDecReports

(see its doxygen documentation)

• I recommend using TriggerTisTos TriggerTisTos TriggerTisTos TriggerTisTos tool instead

HltObjectSummary HltObjectSummary HltObjectSummary

HltObjectSummary class

• Since selected candidates cannot be saved with full info they are summarized

• Same class for all types of candidates

(Particle,RecVertex,Track, anything we add in the future):

– Vector containing either pointers to substructure or LHCbIDs

– Numerical information with a string key identifying type of information:

• Standard Info: same set of variables for each object of the same class (has a “#”

in the label)

• Extra Info: each Hlt1 filter adds one (history of Hlt1 processing)

– Class ID of summarized class (also pointer to the object itself; on-line use only)

• See my talk on Hlt Raw Data at Dec.08 Software Week for more information

Classifying L0 decisions via Hlt1L0 trigger lines

• You can get L0 trigger decisions from L0DUReport

• Each L0 trigger (XXX=Muon, ‘Muon,lowMult’, MuonNoGlob, DiMuon,

‘DiMuon,lowMult’, Hadron, Electron, Photon, LocalPi0, GlobalPi0) has a corresponding Hlt1 pass-through line - Hlt1L0XXXDecision

– True Hlt1 trigger lines. If decision()==true then Hlt1Global decision() must be true as well.

– Heavily postscaled:

• At present one in a million kept

• They convert candidates selected by L0 triggers to Hlt1 type selections

• Postscaling means that they are allowed to fully execute i.e. create candidates if the L0 XXX line succeeded, but the decision turned to false most of the time anyway

• Classifying Hlt1L0XXXDecision decision the normal way (slide 12) not useful since decision()==false essentially all the time

• There is a work around (see next slide)

See slides 5 and 6:

decisionName : Hlt1L0DiMuon,lowMultDecision HltDecReport : { decision : 0 errorBits : 0 numberOfCandidates : 0executionStage : 2 intDecisionID : 14 } decisionName : Hlt1L0DiMuonDecision HltDecReport : { decision : 0 errorBits : 0 numberOfCandidates : 2 executionStage : 6intDecisionID : 12 }

L0 DiMuon,lowMult decision was false L0 DiMuon decision was true

(22)

Classifying L0 decisions

• Compare with slide 12. The differences are highlighted in red.

For Hlt1 developers

• By default only selected candidates by the Decision step of each trigger line are saved

• If you are interested in debugging intermediate Hlt1 selections, you can add them to

HltSelReports by changing configuration of its Maker

from from from

from ConfigurablesConfigurablesConfigurablesConfigurables import import import HltSelReportsMakerimport HltSelReportsMakerHltSelReportsMakerHltSelReportsMaker HltSelReportsMaker().DebugEventPeriod

HltSelReportsMaker().DebugEventPeriod HltSelReportsMaker().DebugEventPeriod

HltSelReportsMaker().DebugEventPeriod = 1= 1= 1= 1

# or

HltSelReportsMaker().MaxCandidatesNonDecision HltSelReportsMaker().MaxCandidatesNonDecision HltSelReportsMaker().MaxCandidatesNonDecision

HltSelReportsMaker().MaxCandidatesNonDecision =500=500=500=500

• You can then use TriggerTisTos tool to access (and classify) their decisions and selected

candidates

(24)

HltVertexReports

• To allow easy access to vertex info (primary vertices, Velo vertices)

without overhead of saving all contributing Tracks (unlike HltSelReports)

• Container of SmartRefVector<LHCb::VertexBase> keyed with the name of the trigger algorithm making RecVertices (e.g. “PV2D”)

– Saved vertices can also be accessed as VertexBase::Container at /Event/Hlt/VertexReports/PV2D/

– Covariance matrix not stored
